Pick out the wrong statement
A.The standard free energy of formation of all element
B.A process accompanied by decrease in entropy
C.The entropy of a perfectly crystalline substance
D.A process that leads to increase in free energy will✓ Correct
Explanation
For a spontaneous process, Gibbs free energy, G 0 . Thus, only those processes that have a natural tendency to decrease free energy are said to be spontaneous.
