The rate of a certain reaction is given by the following rate law: rate = k[N_2]^3[O_3] Use this information to answer the questions below. What is the reaction order in N_2? What is the reaction order in O_3? What is overall reaction order? At a certain concentration of N_2 and O_3, the initial rate of reaction is 7.0 times 10^4 M/s. What would the initial rate of the reaction be if the concentration of N_2 were halved? Round your answer to 2 significant digits. The rate of the reaction is measured to be 63.0 M/s when [N_2] = 0.36 M and [O_3] = 1.8 M. Calculate the value of the rate constant. Round your answer to 2 significant digits.
