Elementary Reaction

The following initial rate data was collected for the reaction, A + 2B $\longrightarrow$ products

B. Find the rate constant

The following initial rate data was collected for the reaction, 2 NO + O$_2$ $\longrightarrow$ 2NO$_2$

[NO$_2$]$^X$[O$_2$]$^Y$

Use the pseudo steady state hypothesis to derive the rate law for the rate of production of P

$E~+~S~\mathop{\leftrightharpoons}^{k_1}_{k_{-1}}~ES$

$ES~\xrightarrow{k_2}~E~+P$

For the proposed mechanism below, identify the intermediates and determine the rate law.

$2~NO_2~+~F_2~\leftrightharpoons~2~NO_2F~~{overall}$

$NO_2F_2+~Br_2~\longrightarrow~NO_2F~+~F~~{slow step}$

$NO_2~+~F~\longrightarrow~NO_2F$
