At high pressure the following reaction is zero order. 2NH3(g)1130K Platinum catalyst N2(g)+3H2(g)Which of the following options are correct for this reaction?

Given, chemical reaction is 2NH3(g)1130K Platinum catalyst N2(g)+3H2(g)At very high pressure reaction become independent of concentration of ammonia, i.e. zero order reaction.Hence, Rate =kpNH30⇒ Rate =k(a) Rate of reaction = Rate constant(c) Rate of decomposition of ammonia will remain constant until ammonia disappears completely.(d) Since, formation of ammonia is a reversible process further increase in pressure will change the rate of reaction. According to Le-Chatelier principle increase in pressure will      favour in backward reaction.
