The rate laws for each of the reactions listed below were obtained at low temperatures. The reactions are highly exothermic and therefore reversible at high temperatures. Suggest a rate law for each of the reactions [(a), (b), and (c)] at high temperatures, which may or may not be elementary.
a. The reaction A → B is irreversible at low temperatures and the rate law is –r_A = kC_A
b. The reaction A + 2B → 2D is irreversible at low temperatures and the rate law is –r_A = kC_A 1/2 CB
c. The gas–solid catalyzed reaction A + B→catC+D is irreversible at low temperatures and the rate law is −rA=kPAPB1+KAPA+KBPB In each case, make sure that the rate laws at high temperatures are thermodynamically consistant at equilibrium.
