2NO xrightarrowN2+O2 textRate=k [NO]2 Hence, order of reaction is 2. H2+I2 xrightarrow2HI Rate=k [H2] [I2] Hence, order of reaction is (1 + 1) = 2 Therefore, these reactions are most likely to be elementary reaction that occur in one step.

$2 NO N_{2} + O_{2}$ $Rate = k [NO]^{2}$ Hence, order of reaction is 2. $H_{2} + I_{2} 2 H I$ $R a t e = k [H_{2}] [I_{2}]$ Hence, order of reaction is (1 + 1) = 2 Therefore, these reactions are most likely to be elementary reaction that occur in one step.
