Calculate the activation energy for a reaction if its rate constant is found to triple when the temperature is raised from $600 . \mathrm{K}$ to $610 . \mathrm{K}$.

Lois did. I were going to be looking at a situation where we have a reaction and the frequency factor is 2.98 times 10 to the 13th. The activation energy is 161 Kalid joules per mole, and the temperature is 600 degrees Celsius. So what would the rate constant be? Well, remember that we have, Ah, a equation that Arrhenius equation which involves all of these components. So why don't we just sort of plug in? Well, first, before we plug in, we have to make some conversions. Let's convert Kalid joules per mole into jewels per mole because our is and jewels and ours also in Calvin. So let's convert that to Kelvin that adding 273. So that would be 100 and 73. So now let's plug in. You've got great. Constant is equal to three 0.98 times 10 to 13th times E to negative 161 1000 divided by eight 0.314 times 800 in 73. So now let's do some math. So a 0.3 point 8.314 times 873 is 7000, 258. It's of I divide 161,000 by that making negative. Now we dio need to that value and then we just multiply that by 3.98 homes tend to the 13th. We will see that I answer is the rate constant is 9200 and 50 number seconds and there we go.

Hi guys. Let's solve problem. 16.59 literate, constant ever given reaction and certain temperature is given. We need to find out the constant and 75 dissensions. So from the Iranian situation we know it is is to now we can compare the our investigation at least two conditions to make a one. Is it due six Women shoes edition and divided by two? Do I do to be a explanation by one? So the defensive factors with reborn and we wouldn't be left week Kate, too Tookie one exponential by two Because this is negative, it reading go up and it really positive divided kingdom. Or we can drink e one x women share a devotedly wanted by the one minus one bank t two. Now it seems that balance given Chianese 4.7 months directed in the 1st 3 second verse one explanations share really discovered evacuation energy from diligent jewels. 3.6 months do the 1st 1 So 3.6 que june 1st 1 divided when the guests constant is eight point 314 Julie morning. First get the 1st 1 Then comes the temperatures. It's gonna want them to give any skill. 25 dissensions means 25 to 98 Children, which he's So do 73 Convince, which is to 98 and 70. Friendly. Listen, she's been 75 to 73 killing, which is 3 48 Children, lips and sound to his values. So 9 to 8 it has been minus one way 3 48 Children. The's gives us okay to seven in the 1st 3 second diverse one. If we do the calculation, we will get exponentially old 1 to 0 for 95 then you and see 10034 my nose. See 0.9 Now the images will be going like this. With the jewels really gone, the walls will be gone and skill wings will be gone. So now if we do the confirmation that it will be 4.79 Worst three second verse one. It's phone in shin 1.95 and this gives us 0.33 It's a universal. Therefore, did it constant and that 75 to 6 years for this given condition is going to be 0.33 2nd verse one

Problem. 61. We were asked to calculate the rate constant given, um, the octave Asian energy, the frequency factor and the temperature. So, um, what I have right here is the arenas aggression, right? And, um, que is already isolated on the left side and were given everything thought we need in terms of variable. So at this point, we just really need to plug in numbers, so our frequency factor is given a right. We got 1.5. I'm Stan reached to 11 for a second times e raised to negative e a right. I have to be a And, um, we'll be using our later, which is in Jewell sperm. All. So, um, in order for our unit, the work e a needs to be converted to Jules Promote. So we're gonna have 56,000 with the 6800 Joe Spur. Over. We got rt. What? So our would be 8.314 Jules promote. Okay, Jules, for more. Okay, Right. And finally we have that temperature 25 the re socialise. And of course, we need to add 273 to that in order to convert it to Calvin. Okay, so 273 plus 25 would be 298. So we got 298 Calvin. Okay, So the reason that I wanted to convert this, um, activation energy through Joe spur more sort out, these units would cancel. This will ask the unit for temperature. Okay, So, um, at this point, we just need to lugging all the numbers and our calculator, and that should give us 17 percent. Okay, And that is our answer for this problem.

I want My name is Billy. The question is the activation energy off reaction is 56.8 kilos. Uber moon and the frequency factor is 1.5. Time 19 bar 11 per second calculates a read constant off reaction and 25 sleaze. Uh oh. Answer this question. We want to really eat the rate Coniston by Activision Energy, which is a related that really posed together is the raid. Constant is equal a time by E power e activation divided by R t So am I. We want to know the K. But first we must know the unit off the K when he's the same as the unit wish. If a year is second per second minus Swan So the key will be second morning a swan which rebooted 1.5 times biting left. So the answer off Kay will be also similar. Second mind now continues aunts Inegative Bari activities. The deactivation is 56 point a booted mine. It's kill a Jew. So when we write the rate which is a guest constant which is the value also killed your which is 8.314 times by 10 negative three when we make it like says it equal by killer Jule to cancel each other times binds that EMP rage if it continues. End of disease is killer Jubeir Morn And these killers. Your pair morn dines. A boy killed. So the temperature on Mars to be killed. So it will be 25. Blast Tau 73 Toby Kelvin. So now all barometer, our knowing by using is a calculator. Zeki will equal 17 and its unit. As I say that first it will be similar. Toe A So it will be 17 2nd bear minus one. Thank you.
