Question

rate k N3 H Use this information to answer the questions below. What is the reaction order in N2? What is the reaction order in H2? What is overall reaction order? At a certain concentration of N2 and H2, the initial rate of reaction is 0.390 What would the initial rate of the your reaction be if the concentration of N2 were answer to 3 significant digits. The rate of the reaction is measured to be 93.0 M/ s when [N21 y 1.1 M and [H2] 0.69 M. Calculate the value of the rate n constant. Round your answer to 2 significant digits.

Explanation / Answer

1 ) order in N2 = 1

2) order in H2 = 2

3) overall order = 1+ 2 = 3

4) if N2 is doubled rate of the reaction is also doubled .

    so rate = 0.390 x 2

             = 0.780 M/s

5)   rate = k [N2] [H2]^2

     93.0 = k (1.1)(0.69)^2

k = 178 M-2 s-1
