Q1. Carbon monoxide is toxic at fairly low concentrations and can cause a range of health issues through long term exposure at much lower levels. Emissions from vehicles need CO levels to be very low and this is achieved with a catalytic converter. 1/2O2(g)+CO(g)CO2(g) The reaction steps for this catalytic reaction are proposed to be: R1:1/2O2(g)+XOXR2:CO(g)+XCOXR3:OX+COXCO2X+XR4:CO2XCO2(g)+X(k1,k1,K1)(k2,k2,K2)(k3,k3,K3)(k4,k4,K4) Derive the rate equation for r CO in terms of bulk concentrations of the gas phase species, forward reaction rates, equilibrium constants, and total active site concentration (Cm) a) Derive the rate equation when R3 is the rate limiting step. b) Derive the rate equation when R4 is the rate limiting step
