The following reaction is exothermic (H= -226 kJ) and has a rate law: Rate = k(NO2)^2: NO2 + CO ? NO (g) + CO2 (g) for each of the following disturbances, indicate whether the rate of the reaction will be FASTER or SLOWER and indicate whether there will be MORE or LESS CO2 at equilibrium. Add more CO: Add more NO: Add a catalyst: Increase the temperature: Decrease the volume of the container:
