The rate of a certain reaction is given by the following rate law: rate = k [H,]°[NH;] Use this information to answer the questions below. What is the reaction order in H2? What is the reaction order in NH3? What is overall reaction order? At a certain concentration of H2 and NH3, the initial rate of reaction is 8.0 x 10* M / s. What would the initial rate of the reaction be if the concentration of H2 were doubled? Round M your answer to 2 significant digits. The rate of the reaction is measured to be 0.610 M / s when [H2] = 1.8 M and [NH3] = 1.8 M. Calculate the value of the -2 -1 k = * = 0M rate constant. Round your answer to 2 significant digits.
