Experiments show that the following redox reactions are second-order overall: (1) NO2(g) + CO(g) --> NO(g) + CO2(g) (2) No(g) + O3(g) --> NO2(g) + O2(g) (a) In reaction 1, the initial [NO2] is twice the initial [CO]. What is the ratio of the initial rate to the rate at 50% completion?(b) In reaction 2, the initial [NO] is twice the initial [O3]. What is the ratio of the initial rate to the rate at 50% completion?
