The possible mechanism for the reaction $2NO + Br_2 \to 2NOBr$ is:
$NO + Br_2 \rightleftharpoons NOBr_2$ (Fast)
$NOBr_2 + NO \to 2NOBr$ (Slow)
The rate law expression is:

Determine True and False from the given statements:
$(a)$ The rate of reaction is directly proportional to the concentration of reactant.
$(b)$ The rate of reaction is inversely proportional to the concentration of reactant.
$(c)$ The rate of reaction does not depend on the concentration of reactant.

For a reaction $2 \ A + B \rightarrow P$,when the concentration of $B$ alone is doubled,the rate does not change,and when the concentrations of both $A$ and $B$ are doubled,the rate increases by a factor of $4$. The unit of the rate constant is,

Rate law for a reaction is $r=k[A]^2[B]$. If rate constant is $6.25 \ mol^{-2} \ dm^6 \ s^{-1}$,what is the rate of reaction when $[A]=1 \ mol \ dm^{-3}$ and $[B]=0.2 \ mol \ dm^{-3}$?

If the half-life of a reaction is halved when the initial concentration of the reactant is doubled,what is the order of the reaction?
