Entropy

Question 1

Will ^H negative and ^S positive be feasible ?

Answer 1

Yes - reaction is exothermjc and entropy has increased so will always be feasible

Question 2

Will ^H positive and ^S negative be feasible ?

Answer 2

Reaction is endothermic and entropy has decreased so not feasible

Question 3

Will ^H negative and ^S negative be feasible ?

Answer 3

Hard to predict as ^H favours the reaction but -T^S is positive so resists the change
