To know where the oxidation to know where the oxidation off s in two plus a curious bye bra mean Aquarius is spontaneous, are not so. And this reaction at a nod is in two plus oxidizes in tow sn four plus releasing two electrons. So the oxidation for this reaction is minus 0.154 is the reelection value is let's 0.15 To write the reaction in the reverse direction and change the e reelection value toe e oxidation, we will change the sign. So we have put the sign minus 0.15 It gets old reduction off the bro. Mean will take place, which will get the two electrons and will form the two bromide sign. So the e reduction for the Brahmins is plus 1.9 world toe. Find the SL. We will add the two equations s n two plus plus PR toe. We can cross the electrons so from s and four plus and tau B R minus where in order off the cell is the sum of the elbow e oxidation and reduction values which is equal to zero plying nine for world now to calculate Delta Jean Art, which is ableto mind us and if in art is and is the number of electrons last and again, which is equal toe to moles up electrons. If it's Ferrari Constant, which is 96,500 Coolum per moral of electrons and YSL, we can write 0.94 world and stayed up world. We can write Joel per column as one World is equal toe. One job for Coolum Putting the values in the equation. We will get minus toe more lap electrons and 96,500 Coolum Par moral of electrons multiply by 0.9 for Jowell Pirkle Um we can cross the Coolum and moral of electrons multiplying the values we will get minus 181 4 to 0 Jowell, change it and kill our job. We will divide this value by 1000 so we will get Delta Jeannot minus 181.42 Killer job is Delta G not his negative your value while energy his positive value Therefore the reaction is spontaneous. This is the required solution to this question. Find where the reduction we had the reduction off nickel two plus on and by the S and two plus iron is on 10 years are not we can like that s n two plus we'll oxidizes and toe s and four plus and we'll release two electrons or the oxidation potential for this reaction is minus 0.15 fold Where an i two plus well again, two electrons to change and to nickel. So the e reduction for the nickel is also minus 0.26 world combining both equations So s n two plus react with and I two plus farm It's in formless and nickel zero acceleration state he off the cell is equal toe e oxidation plus the reduction adding the values we will get minus zero point for one world or to find out Delta Jeannot for the reaction which is equal to minus. And if in our where n is the number of electrons which is to moles up electrons, if it's fill out a constant, which is 96,500 Cool um Parmalat electrons and the off the cell is minus zero point for one Jowell Pirkle, um is one world is one Joel per Coolum putting the values we will get minus to moral of electrons and 96,500. Cool. Um, Carmela electrons and e not is minus zero point for one job per kulum. We can cross the units we will get, so we will get that it is equal toe plus 79130 Jowl toe change and kill legible dividing by 1000. So we will get plus 7, 9.13 kill a job. This is Delta Jeannot, for this is Delta Jean Art has positive value and energy has negative value. This is the case for the non spontaneous reaction. So the reaction is non spontaneous. In the third case to find where the reduction off are you lean. Bye Age toe s or three This on 10 years are not so. And this reaction the oxidation off the H to s 03 in the presence of water, take place toe form IHS or for tu minus plus four hydrogen ions and four electrons are released. The oxidation for this reaction is minus 0.17 world while on the other hand, two iodide a Irene can the four electrons, um, for hired eyes. So the the reduction for the Irene is 0.54 world. Now, combining the two equations, we will get that H two s 03 right h to s or three react with the I Odeen and the presence off water. We can cross the electrons on either side. So we will get that for iodide. Ions are formed sulfate fine. And for hydrogen eyes, he not off the cell is equal to the sum of the e oxidation, plus the reduction so that some of the two values is zero plein three stay one world No. So find Delta Jean Art, which is equal to minus. And if he not we're in is the number of electrons last endgame? So the total number of electrons last and again in the reaction is for malls of electrons. If it's fill out a constant, which is 96,500 Coolum par moral of electrons and energy in this case is 0.37 world. So I and stood up we can Joel Pirkle, um is one world is equal toe one putting the values minus. We're Ennis for malls off electron fs Ferrari constant 96,500 Coolum part Moeller electrons. And in art is 0.37 Joel purple. Um, cutting The units are born below. We can get the delta. Jeannot is equal toe minus delta. Jeannot is equal to minus 142 a 20 Jowell toe change Trento kill a job. We were divided by thousands or minus one 42.82 Killer Joe, this is Delta Jean Art. As Delta Jeannot has a negative value while energy his positive value. This is the case for spontaneous reaction. So the reaction A spontaneous reaction. This is the required solution to this question. No, in the case where the oxidation off silver bye lead on spontaneous are not so In this case, the silver has bean oxidizes in tow. Silver I'll the silver has bean oxidizes and two silver iron reducing tau electrons. So the e oxidation for the silver is minus 0.80 world while the lead on has bean reduced and toe PB. So the reduction for this is equal toe minus 0.13 word to write the Net equation And to find the easily so to a D react with Pee Wee to place. We can cross the electron on either side from two a. D plus and I let ah, Adam e not off. The cell is equal toe the e oxidation, plus the reduction, which is equal to minus 0.93 world toe. Find Delta Jeannot for this reaction, which is equal to minus. And if en art as and as the number of electrons, which is two moles up, electron last and again in this reaction, if it's filler the constant, which is 96,500 cool, um, per mole of electrons and in art up the sale and stood up World weekend rightto minus 0.93 and stood up World weekend right job per column, general particular is one world is equal toe one child for cool. Um, putting The values were here and the Delta Jean Art. We will get minus mola electrons and 96,500 Coolum Parmalat electrons and tow energy is minus 0.93 child per column, getting the units above and below. So Delta Jean art is equal toe plus adding multiplying the negative sign with order, son will be posited you plus 179 490 Jowell and change it in tow. Kill a job. We were divided by 1000. So they're dajun r is equal 179.49 Hello, John. Is Terry Taji not his positive value. While in art, off the cell is negative value, which is the condition for the non spontaneous reaction. This is the required solution to this part of the question.
