What is the Rate Law

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$_2$]$^Y$

Below is a proposed mechanism for a reaction, with k1 > k2. What is the rate law?

$NO+ Br_2~ \mathop{\leftrightharpoons}^{k_1}_{k_{-1}}~ NOBr_2$

$NOBr_2 + NO~ \xrightarrow{k_2}~ NOBr + NOBr$

For the mechanism proposed below, determine the overall rate law for k$_1$ < k$_2$, k$_1$ > k$_2$

$2~NO~+~2 H_2~\longrightarrow~2~H_2O~+~N_2~~{overall}$

$2~NO+~H_2~\mathop{\leftrightharpoons}^{k_1}_{k_{-1}}~N_2O~+~H_2O$

$N_2O~+~H_2~\xrightarrow{k_2}~N_2~+~H_2O$
