The decomposition of ${\mathrm{N}}_2{\mathrm{O}}_5$ by

$2{\mathrm{N}}_2{\mathrm{O}}_5\to 4{\mathrm{NO}}_2 + {\mathrm{O}}_2$follows first order kinetics.

Hence,

 

The hydrolysis of ester in alkaline medium is 

The reaction $2\mathrm{Na}+{\mathrm{Cl}}_2\stackrel{ }{\to }2\mathrm{NaCl}$ is found to follow 3rd order kinetics, its molecularity is 

If '$\mathrm{a}$' is the initial concentration of a substance which reacts according to zero order kinetic and '$\mathrm{k}$ ' is rate constant the time for the reactant to go to completion is,

When ${\mathrm{AgNO}}_3$ solution is added to aqueous $\mathrm{NaCl}$, a white precipitate is obtained. This reaction is:

The rate law for the reaction

$2\mathrm{A}+\mathrm{B}\to 2\mathrm{C}$  is represented as,

Rate $=\mathrm{k}{\left[\mathrm{A}\right]}^2 \left[\mathrm{B}\right]$. If A is taken in large excess, the order of the reaction will be,

If the rate of reaction between $\mathrm{A}$ and $\mathrm{B}$ is given by, rate $=\left[\mathrm{A}\right] {\left[\mathrm{B}\right]}^2$, then the reaction is,
