How will each of the following affect the rate of the reaction: CO(g)+NO2(g)CO2(g)+NO(g) if the rate law for the reaction is: Rate=k[NO2][CO] (a) Increasing the pressure of NO2 from 0.1atm to 0.3atm ? Explain using order. (2 marks) (b) Increasing the concentration of CO from 0.02M to 0.06M. Explain using order. (2 marks) 5.
