Which statement is true?
a. A reaction in which the entropy of the system increases can be spontaneous only if it is exothermic.
b. A reaction in which the entropy of the system increases can be spontaneous only if it is endothermic.
c. A reaction in which the entropy of the system decreases can be spontaneous only if it is exothermic.

So we're given three scenarios will determine which one is true. So in scenario, a entropy of the system increases. So the doctor s equals positive. Now we can stop right there and look at our reaction. Delta G equals that H finest Ito s. Now, if don't s is positive, then this number is negative. So even if Delta H is positive, this reaction can still be spontaneous is on This tea is large enough. I remember you. You won't delta t to be negative for the reaction. Be spontaneous. So this could be spontaneous. Only his exit permit. It's not true. So this one is not the one we're looking for. Question be and shred. The system increases again. So we already know that it doesn't matter what sign Delta H is. As long as T is large enough, Delta G will still be negative because Delta s is positive. So it is not dependent on Delta H. There is not only dependent on the h. It can also be effected by t. This one's also false. So a process of elimination would give us see? Let's just work through it to make sure we understand. Don't s is negative because the system decreases in entropy. And so, in this case, Delta G. Who was that? The H honesty. Don't s everyone. Don't Could you be negative? If Delta s is negative, then this value is now positive. So it does. H must be negative for there to be any chance for adult egy to be negative, Which means that has can only be spontaneous if it is except thermic. So this one is true, Like to point out that not only must don't h b negative or ex a thermic, but he also must be very small. So that's no negative value is larger than its positive value.

Right. So here's the problem. 20 to 4, Chapter 19. This is a true or false questions. Part eight. The entropy of the universe increase for any spontaneous process. This is true. And this is what the second law of thermodynamics states. Yeah. 2nd 1 this is false. This is because the entropy change of the system is equal. And opposite that up, the surrounding owning for reversible process, not for irreversible process part. See, the entropy of the system must increasing any spontaneous process. This is false for a reaction to be spontaneous or not, we're looking at the Delta Ji Valuable and Delta Ji depends on both Delta H tea and deltas. So the change of entropy is not necessary to be positive because that's what she also depends on other terms. Last one, the entropy change for isil thermal process. So the entropy change front. I saw thermal process is simply equal to Q divided by tea, or this one represents the heat transferred reversible lea to the system. And this is the absolute temperature so that entropy change. Frances Norma process depends both on absolute temperature than and the amount of heat reversible he transferred is correct.

Here we are looking to assess the validity of a few different statements under the umbrella of the islamo dynamic content. And so the first one. This is a false statement and this is false because the entropy change, which is the heat of reaction has no direction. So this is false for me. This is also false, and we can discuss why. So the rate of the reaction doesn't have anything to do with the spontaneity, which is the thermodynamics. And so next week and look at parts see which is another false statement. So the entropy may increase or decrease during a spontaneous reaction with part D. This is true. So the entropy of the system at the surroundings always increases during a spontaneous change. And finally we have another false and we can discuss why. So the energy may increase or decrease during the spontaneous reaction. And so that statement is false.

This question wants you to simply identify whether or not the following statements are true or fault. The first statement is a spontaneous reaction always releases heat. This is false. If it's going to release heat than delta H is going to be negative, but there's still the component for it to be spontaneous of minus T delta as So we do want delta G to be negative. It's favorable if DELTA H is negative, but we could have a negative delta S. That gives us a positive contribution greater than this, giving us a positive delta G. So not all spontaneous processes release heat, statement B A spontaneous reaction is always a fast reaction. This is also false, spontaneous just means that there's a favorable change in energy. It says nothing about the rate of the reaction. So you never want to make the mistake of linking a favorable thermodynamic process with a fast reaction. Some of them are fast. Some of them are slow. Like its thermal dynamically favorable in order for for a diamond to become graphite. But it's really slow statements see, the entropy of a system always increases for a spontaneous change. This is also false. Again, going back to this equation here, if entropy is going to increase, we're going to get a positive delta S here, but it may be for an end to thermic process where this is positive. Still resulting in a positive delta G. So the entropy of a system does not always increase for a spontaneous process. What does increases the entropy of the universe. That is true for a spontaneous process, statement D the entropy of the system and its surroundings always increases for a spontaneous change. So I assume that they're referring to delta's universe, where the delta asks of the system plus the delta S. Of the surroundings is positive. So the entropy of the system plus its surroundings always increases for a spontaneous change. In this case. That would be true. And, statement E the energy of the system always increases for a spontaneous change. Yeah, this is false. If we're talking about the energy of the system in terms of its free energy DELTA G. Than for a spontaneous process, delta G is always going to be negative and decrease rather than increase.
