(a) Does the entropy of the surroundings increase for spontaneous processes?

Video transcript

Hello. In this problem we are told that for a spontaneous reaction, the entropy of the surroundings will not change Grass. Is this statement true or false, recall that the change in entropy of the universe is equal to the change in entropy of the system. Plus the change in entropy of the surroundings. The change in entropy of the universe will be greater than zero. When we have an irreversible reaction that is spontaneous and the change in entropy of the universe will be equal to zero when we have a reversible reaction that is at equilibrium. So all we know about a spontaneous reaction is that change in entropy of the universe needs to be greater than zero. Change in entropy of the system and the surroundings are not known for certain without performing a calculation or carrying out an experiment. So the answer to this question then is false, which corresponds to answer B. Thanks for watching. Hope. This helped.
