384 mol L–1s–1 This
indicates that the rate depends upon the square of the concentration of
NO When concentration of NO is kept constant and concentration of
O2 is doubled the rate also gets doubled indicating that rate depends
on concentration of O2 to the first power Hence, the rate equation for
this reaction will be
Rate = k [NO]

Now, we observe that for this reaction in the rate equation derived
from the experimental data, the exponents of the concentration terms
are the same as their stoichiometric coefficients in the balanced
