(A) DG = 0, DS = +ve
(B) DG = 0, DS = -ve
(C) DG = +ve, DS = 0
(D) DG = -ve, DS = +ve
4. Consider a reaction aG + bH → Products. When concentration of both of the reactants G and H is doubled, the rate increases by eight times. However, when concentration of G is doubled keeping the concentration of H fixed, the rate is doubled. The overall order of the reaction is
