The mechanism of esterification in presence of acid catalyst $\left(H_{2}S{O}_4\right)$ is proposed as follows:



Which of the following potential energy vs reaction co-ordinate diagram is consistent with given mechanism?

The reaction rate for the reaction

${\left[{\mathrm{PtCl}}_4\right]}^{2-}+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\left[\mathrm{Pt}\left({\mathrm{H}}_2\mathrm{O}\right){\mathrm{Cl}}_3\right]}^{-}+{\mathrm{Cl}}^{-}$

was measured as a function of concentrations of different species. It was observed that

$\frac{-\mathrm{d}\left[{\left[{\mathrm{PtCl}}_4\right]}^{2-}\right]}{\mathrm{dt}}=4.8\times {10}^{-5}\left[{\left[{\mathrm{PtCl}}_4\right]}^{2-}\right]-2.4\times {10}^{-3}\left[{\left[\mathrm{Pt}\left({\mathrm{H}}_2\mathrm{O}\right){\mathrm{Cl}}_3\right]}^{-}\right]\left[{\mathrm{Cl}}^{-}\right]$

where square brackets are used to denote molar concentrations. The equilibrium constant

${\mathrm{K}}_{\mathrm{c}}=X$(Nearest integer)

Value of $\frac{1}{X} is$ (question is modified.)

The reaction $2\mathrm{NO}+{\mathrm{Br}}_2\to 2\mathrm{NOBr}$ takes place through the mechanism given below

$\mathrm{NO}+{\mathrm{Br}}_2\stackrel{}{\rightleftharpoons }{\mathrm{NOBr}}_2 \left(\mathrm{fast}\right)$

${\mathrm{NOBr}}_2+\mathrm{NO}\to 2\mathrm{NOBr} \left(\mathrm{slow}\right)$

The overall order of the reaction is _____.

The reaction $2 \mathrm{A}+{\mathrm{B}}_2\to 2\mathrm{AB}$ is an elementary reaction.

For a certain quantity of reactants, if the volume of the reaction vessel is reduced by a factor of $3,$ the rate of the reaction increases by a factor of _____ . (Round off to the Nearest Integer).

Consider the following reaction that goes from $\mathrm{A}$ to $\mathrm{B}$ in three steps as shown below:
