The given graph is a representation of kinetics of a reaction.

The $\mathrm{y}$ and $\mathrm{x}$ axes for zero and first order reactions, respectively are

For a first order reaction $\mathrm{A}\to$ Products, initial concentration of $\mathrm{A}$ is $0.1 \mathrm{M}$, which becomes $0.001 \mathrm{M}$ after $5$ minutes. Rate constant for the reaction in ${\min }^{-1}$ is

For a reaction $\mathrm{A}\to \mathrm{B},$ enthalpy of reaction is $-4.2 \mathrm{kJ} {\mathrm{mol}}^{-1}$ and enthalpy of activation is $9.6 \mathrm{kJ}{ \mathrm{mol}}^{-1}.$ The correct potential energy profile for the reaction is shown in the option.

The slope of Arrhenius Plot $\left(\mathrm{lnk}\text{ v/s }\frac{1}{ \mathrm{T}}\right)$ of first order reaction is $-5\times {10}^3 \mathrm{K}.$ The value of ${\mathrm{E}}_{\mathrm{a}}$ of the reaction is. Choose the correct option for your answer.

[Given $\mathrm{R}=8.314 \mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}$]

The half-life for a zero order reaction having $0.02 \mathrm{M}$ initial concentration of reactant is $100 \mathrm{s}$. The rate constant (in $\mathrm{mol} {\mathrm{L}}^{-1}{\mathrm{s}}^{-1}$) for the reaction is

In collision theory of chemical reaction, $Z_{\mathrm{AB}}$ represents

The rate constant for a first order reaction is $4.606\times {10}^{–3}{\mathrm{s}}^{–1}$. The time required to reduce $2.0\mathrm{g}$ of the reactant to $0.2\mathrm{g}$ is :

An increase in the concentration of the reactants of a reaction leads to change in
