Detailed Solution
(1) ΔG∘=−2.303 RT logKcSince, Kc remains unchanged in the presence of a catalyst, thus ∆G° is not affected correct.(2) In the presence of catalyst, reaction path of lower activation energy is taken Correct(3) In the presence of catalyst, reaction path of lower activation energy is taken Correct.(4) Nor spontaneous reactions are not catalysed. correct.
