Vedclass · Answer

(C) Entropy is a measure of the randomness or disorder of a system. $\Delta S In option $A$,solid to gas transition increases disorder. In option $B$,dissolution increases entropy due to mixing. In option $D$,mixing of gases increases entropy. In option $C$,two moles of gaseous reactants form one mole of solid product. Since the solid state is much more ordered than the gaseous state,the entropy of the system decreases.

Which of the following processes takes place with a decrease of entropy?
