The reaction 2 NO(g) + 2 H2(g) rtarrow.gif N2(g) + 2 H2O(g) was studied at a certain temperature with the following results:

Experiment [NO(g)] (M) [H2(g)] (M) Rate (M/s)
1 0.0867 0.0867 71.7
2 0.0867 0.173 143
3 0.173 0.0867 285
4 0.173 0.173 570.


(a) What is the rate law for this reaction?

Rate = k [NO(g)] [H2(g)]

Rate = k [NO(g)]2 [H2(g)]   

Rate = k [NO(g)] [H2(g)]2

Rate = k [NO(g)]2 [H2(g)]2

Rate = k [NO(g)] [H2(g)]3

Rate = k [NO(g)]4 [H2(g)]

(b) What is the value of the rate constant?

(c) What is the reaction rate when the concentration of NO(g) is 0.141 M and that of H2(g) is 0.177 M if the temperature is the same as that used to obtain the data shown above?
