Answer 1

For the process H2O(l) → H2O(g) at 1 bar 373k the correct set of thermodynamics parameters is ΔG= 0 and ΔS = + ve

ΔG This is change in gibbs free energy

ΔS This is change in entropy

Entropy is a measure of disorder of a reaction.

Gibbs free energy determines the spontaneity of a reaction that is whether the reaction will be spontaneous or not.

If Gibbs free energy is positive, the reaction is non-spontaneous and if it is negative, the reaction is spontaneous.
