Question

Of following reactions, which one(s) would you expect to have a negative AS? Br + Br2 Br OH CI + HCI IV Br

Answer 1

Answer #1

Reaction I, since no of product are less in no than no of reactants., hence change in entropy is negative. Since entropy is the measure of disorder.

For Reaction II and IV entropy is zero ie., no change

For reaction III, it is positive since no of products are more than reactants.
