3. To remove oxides of nitrogen (assumed to be NO ) from automobile exhaust, a scheme has been proposed that uses unburned carbon monoxide (CO) in the exhaust to reduce the NO over a solid catalyst, according to the reaction CO+NO Products (N2,CO2). Experimental data for a particular solid catalyst indicate that the reaction rate can be well represented over a large range of temperatures by rN=(1+K1PN+K2PC)2kPNPC where PN= gas-phase partial pressure of NO PC= gas-phase partial pressure of CO k,K1,K2= coefficients depending only on temperature (a) Determine if the following rate law will explain the experimentally observed kinetics. NO+SNOSCO+SCOSNOS+COS0.5N2+CO2+2S (b) A certain engineer thinks that it would be desirable to operate with a very large stoichiometric excess of CO to minimize catalytic reactor volume. Do you agree or disagree? Explain
