The rate of reaction is always equal to the rate constant. The order of the reaction will be

For the reaction, ${\mathrm{H}}_2{\mathrm{O}}_2+2{\mathrm{H}}^{+}+3{\mathrm{I}}^{-}⟶{\mathrm{I}}_3^{-}+2{\mathrm{H}}_2\mathrm{O}$

Select the correct statement

$2\mathrm{A}+\mathrm{B}⟶\mathrm{C}+\mathrm{D}$

In this reaction, if we double the concentration of $\mathrm{A}$, reaction rate become two times. And in other experiment, we double the concentration of $\mathrm{A}$ and $\mathrm{B}$, reaction rate again become two times. What is the order of this reaction?

In a first order reaction, on plotting a graph between ${\mathrm{t}}_{1/2}$ and concentration of reactant

In data given below

The reaction may be
