Question

What is the rate of the following reaction (M/s) if the rate constant for the reaction is 0.500 L•mol-1•s-1 and the concentration of each reactant is 0.0628 M. (The units for the rate constant depend upon the rate law).
CO + NO2 --> CO2 + NO

Answer 1

The units tell you this is a second order reaction rate.An order of 1 for CO and 1 for NO2 would mean
rate = 0.500*(0.0628)(0.0628)
