Predicting sign of entropy change
WebThe entropy change of the universe can be broken up into two parts, the entropy change of the system and the entropy change of the surroundings: D S univ = D S syst + D S surr. D S syst, the entropy change of the system, represents the change in order of the molecules of the system, similar to what was discussed in Entropy 2. WebConversely, lower temperatures lower the entropy of a system. Remember, this is the temperature of the system, not the surroundings. So, an endothermic reaction will …
