$3Br_2 + 6CO_3^{2-} + 3H_2O \longrightarrow 5Br^-+ BrO_3^-+ 6HCO_3^-$
Which of the following statements is true regarding this reaction
In the above first order reaction the concentration of $\mathrm{PCl}_{5}$ reduces from initial concentration $50\, mol\,\mathrm{L}^{-1}$ to $10\, \mathrm{~mol} \,\mathrm{~L}^{-1}$ in $120\, minutes$ at $300\, \mathrm{~K}$. The rate constant for the reaction at $300\, \mathrm{~K}$ is $\mathrm{X}$ $\times 10^{-2} \mathrm{~min}^{-1}$. The value of $x$ is $......$
$[$ Given $\log 5=0.6989]$
the time taken for $75 \%$ reaction of $P$ is twice the time taken for $50 \%$ reaction of $P$. The concentration of $Q$ varies with reaction time as shown in the figure. The overall order of the reaction is
