We're being asked to determine the rate law for the following reaction:

2 H2(g) + 2 NO(g) → 2 H2O(g) + N2(g)

Recall that the rate law only focuses on the reactant concentrations and has a general form of:

k = rate constant
A & B = reactants
x & y = reactant orders

Problem Details

The reaction

2H2(g) + 2NO(g) → 2H2O(g) + N2(g)

is known to be first-order in H2 and second-order in NO at a particular temperature.

What is the rate law?

A) Rate = k[H2]2[NO]2

B) Rate = k[H2][NO]2

C) Rate = k[H2][NO]

D) Rate = k[H2O]2[N2]

E) Rate = k[H2]2[NO]
