Two reactions in which there is a single reaction have nearly the same magnitude rate constant. Reaction A is first order, reaction B is second order. A) if the initial concentrations of the reactants are both .30 M, what is the ratio of the rate of reaction A to reaction B ? B) if the initial concentrations of the reactants are both 1.80 M, what is the ratio of the rate of reaction A to reaction B ?
