Applying half life method to find order of reaction given below
$\frac{{\left({\text{t}}_{\text{1/2}}\right)}_{\text{1}}^{\text{2}}}{{\left({\text{t}}_{1/2}\right)}_{\text{2}}}\text{=}{\left(\frac{{\text{a}}_{\text{2}}}{{\text{a}}_{\text{1}}}\right)}^{\text{n}-\text{1}}$
$\frac{1.82}{0.91}={\left(\frac{50}{25}\right)}^{\mathrm{n}-1}$
$2=2^{\mathrm{n}-1}$
or$\text{n }-\text{1 = 1}$
$\text{n = 2}$.
