The rate of a certain reaction is given by the following rate law: rate=k[Hz]> [NH3] 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? M At a certain concentration of H2 and NH3, the initial rate of reaction is 91.0 M/s. What would the initial rate of the reaction be if the concentration of H2 were doubled? Be sure your answer has the correct number of significant digits. OM S -2 -1 The rate of the reaction is measured to be 0.640 M/s when [H2] = 1.1 Mand (NH3] = 0.63 M. Calculate the value of the rate constant. Be sure your answer has the correct number of significant digits. k = IM
