Consider the unimolecular reaction CH3NC(g)-->CH3NC(g), carried out in the presence of a helium buffer gas. The collison collison og a CH3NC molecule with either another CH3NC molecule or a helium atom can energize the molecule thereby leading to a reaction. If the energizing reactions involving a CH3NC molecule and a He atom occur with different rates, the reaction mechanism would be given by(picted below). Apply the steady state approximation to the intermediate species, CH3NC*, to show that rate=d{CH3CN}/dt=k3(k1{CH3NC}^2+k2{CH3NC}{He}/k1'{CH3NC}+k2'(He)+k3 Additionally determine the rate law when {He}=0
