The initial rate of the following reaction was measured at different starting concentrations of NO and H2:

2NO(g) + 2H2(g) -> N2(g) + 2H2O(g)

Using the data, which of the following represents the rate law for this reaction?

a. Rate = k[NO]2[H2]2
b. Rate = k[NO][H2]
c. Rate = k[NO][H2]2
d. Rate = k[NO]2[H2]
