The Equation, G = H − TS , Predicts That

Question

The equation, G = H − TS , predicts that
A) metabolism decreases proportionately to anabolism.
B) metabolism increases proportionately to catabolism.
C) as enthalpy decreases, the amount of entropy also decreases.
D) as entropy increases, the amount of free energy decreases.
E) as enthalpy increases, the amount of free energy increases.

Accepted Answer

The equation G = H - TS (where G is Gibbs free energy, H is enthalpy, T is temperature, and S is entropy) shows that as entropy (S) increases (with T being constant), the term TS increases, which means the amount of free energy (G) decreases, assuming H is constant.
