Homework Answers
Answer: As we know the equation of entropy, enthalpy and temperature as-
G
=
H - TS
If the
H is independent of temperature then
H can be ignored.
G
= - TS
As per this equation if the value of Temperature (T) increases
G value also increases towards more negative side.
As, more the negative
G, more spontaneous is the reaction
hence the reaction is spontaneous this means product formation predominent.
Hence answer is (a) shifts the equilibrium towards product

Physical Chemistry rate law reverse reaction expression help?
thank you!
Suppose a reaction A rlhar B can produce B via two pathways - an uncatalyzed pathway with a rate k_af[A] and a OH^- catalyzed pathway with a rate of k_bf[OH^-][B]. Given the equilibrium constant K = [B]_eq/[A]_eq and that the rate law is v_f = (k_af + k_bf[OH^-])[A] = k_f[A], find an expression for the corresponding rate law for the reverse reaction.
