Determine the rate of the chemical reaction shown directly

.         Determine the rate of the chemical reaction shown directly below, given an NO concentration of 5.0 x 104 M, an H₂ concentration of 8.0 x 102 M, and a rate constant k of 1.1 x 10^-2M²s¹

The rate law for this reaction is rate = k [NO]²[H₂]

    2NO + 2H₂ N₂ + 2H2O

Solution

rate =K [NO]² [H2]

substitute K , NO and H2 values.

rate = 1.1 x 10^-2 [5.0 x 10^-4]² [5.0 x 10^-4]

rate = 1.38 x 10^-12 M/s
