Given the fact that the enthalpy of formation deltaH and Gibbs free energy deltaG is zero for a pure substance in their natural phase under standard condition,
and the equation deltaG=deltaH - TdeltaS,
why isn't the deltaS (also known as change in standard molar entropy in this case) also zero for a pure substance in their natural phase under standard condition?
Or is it supposed to be zero?
