Determine whether the statements given below are true or false. Consider enthalpy $(H)$. (a) It is a state property. (b) $q_{\text {reaction }}($ at constant $P)=\Delta H=H_{\text {products }}-H_{\text {reactants }}$ (c) The magnitude of $\Delta H$ is independent of the amount of reactant. (d) In an exothermic process, the enthalpy of the system remains unchanged.

Here we are continuing on to look at the content related to former dynamics and like a few videos previous, we are looking at true and false statements so we'll identify statements where they are true and if they're false will explain why to impart a we have a true statement in Part B. This is also true. However, part C is false. The magnitude of the end will be changed, depends upon the amount of reactant participating in the reaction. And finally party is another false statement. So in an exhaust comic process, the entropy of the system decreases as the entropy of product is lower than the reactant, so therefore the entropy change. Delta H. Is negative for an exit thermic reaction. So there we had four statements, two of which were true, two of which were false. And we corrected their falsehoods.

So we're gonna go ahead and answer some questions here about an exotic thermic reaction. Okay, eggs are thermic is when Q. Is negative. All right. So the temperature of the water would increase. Well, yes. Okay, this is going to be true. So, for an exotic thermic reaction, the energy goes from the system out into the surroundings, which is your water. So that's actually going to get hotter. We'll see an increase in temperature there. Okay. And then heat is absorbed by the water. Okay, So this is also true again where the energy is going from the system, out into the surroundings. Okay. And part of the surroundings is our water. Okay, So energy is actually being absorbed by the water. So that's true as well. All right. The entropy of the products is higher than the reactant. Well, we've got our reactant give us our products plus some energy. Okay, So it looks like actually the reactant have the higher in therapy. So this is going to be false. Yeah. So, the heat of the water equals the heat of reaction. This is almost true, but not quite. Okay. The heat gained by the water equals negative heat of reaction. Okay, So this is actually going to be false. You need the negative sign in there to make that true. All right. The heat of reaction. Okay. We want to know. Is it greater than zero? Well, since its eggs a thermic. All right. Q. Is actually negative. So it's actually gonna be less than zero. So this is false. And then finally, the heat of the reaction plus the heat of the water. So the heat lost by the reaction plus the heat gained by the water equals zero. Mhm. Well, this is true. It's the same thing as saying the heat of reaction he lost by the reaction equals negative. The heat gained by the water. Okay, so this is a true statement.

What is true about an exit? Thermic reaction. EXA Thermic reactions involve the release of energy and has a net negative standard. Entropy change. Yeah, So we can say the products have lower potential energy than the reactant.

This question asks for which statement is true regarding an Excel Obama's reaction. I just briefly go over the concept of Exeter Mick Reaction. So first we have a reaction, which probably captains four main products and the logistical into their their potential energy. Let's say there are two different states. One has a high potential energy, and one has a lower potential energy. If the reactant have a higher potential energy and the products have a lower potential energy, then from the reactant to product, it is considered a excellent thermic reaction. And during this reaction, energy will be released. And if the reactions of a lower potential energy state and the products have a higher potential energy state from the attends to product, this is considering exo or endo. Thermic reaction and energy is required for this reaction, meaning that it needs outer source of energy. So let's go over the option and see which one is the crypt. Eight talks about that the products have a lower potential energy than the reactant. So as we know that products for an exo thermic reaction, the products have a lowers potential energy, and the reactors have a higher potential energy. Therefore, auction A is the correct answer, and for option B energy it talks about energy must be added to the reaction on. We know that for an extra term of reaction, energy is released on a foreign endo thermic reaction, and then g must be added. Therefore, it is talking about the end author make, and it is not correct for an ex atomic reaction. And for Option C, it talks about the entropy and for Exeter, make an endo thermic reaction. It is talking about the potential energy state off the reaction, and it's not talking about the entropy stayed on. That reaction can be Exeter my core and do thermic regardless of its entropy. Stay there. Fourty entropy part is irrelevant. And this a question. And for Option D, it talks about the rate of reaction, and the reaction can be Exeter make or and no thermic, regardless of its rate and rate, is not directly determined by the energy state. Therefore, it is incorrect. So the correct answer for this question is option a
