Read the following industrial methods for the preparartion of H_(2)SO_(4) and answer the question at the end. Professor Molina of the Massachusetts Institute of Technology won the 1995 Noble prize in Chemistry for his work on atmospheric chemistry . One reaction that he studied in detail is the acid rain reaction which produces H_(2)SO_(4) in the atmosphere. He proposed two possible stoicchiometric reactions: Proposal A: H_(2)O(g) +SO_(3)(g) rarr H_(2)SO_(4)(g) Proposal B: 2H_(2)O(g) +SO_(3)(g) rarr H_(2)SO_(4)(g) +H_(2)O(g) Using the simple collision theory, what reaction orders would be expected for proposal B? ProposalB is thought to proceed by the following two-step process: SO_(3)+2H_(2)Ounderset(k_(-1))overset(k_(1))hArr SO_(3).2H_(2)O""(Fast) SO_(3).2H_(2)O overset(k_(2))rarr H_(2)SO_(4)+H_(2)O "" (slow) (SO_(3).2H_(2)O is a complex which is stabilized by hydrogen bonds and k_(2) lt lt k_(1) or k_(-1))
