What is molecularity of a relation ? Explain its types by examples.

The following mechanism has been proposed for the reaction of $NO$ with $Br_2$ to form $NOBr$ :

$NO(g) + Br_2 (g) \rightleftharpoons NOBr_2 (g)$

$NOBr_2(g)+ NO(g) \longrightarrow 2NOBr(g)$

If the second step is the rate determining step, the order of the reaction with respect to $NO(g)$ is

In a gaseous reaction 

${A_{2\left( g \right)}} \longrightarrow {B_{\left( g \right)}} + \frac{1}{2}\,{C_{\left( g \right)}}$ the increase in pressure from $100\, mm$ to $120\, mm$ is noticed in $5\,\min$. The rate of dissappearence of $A_2$ in $mm\, min^{-1}$ is

For the following reaction scheme (homogeneous), the rate constant has units

$A+B\xrightarrow{K}C$:

For the reaction $A + 2B \to C,$ rate is given by $R$ $ = [A]{[B]^2}$ then the order of the reaction is
