$\mathrm{K}=\mathrm{A} {\mathrm{e}}^{-\frac{{\mathrm{E}}_{\mathrm{a}}}{\mathrm{RT}}}$ is Arrhenius equation. It gives variation of rate constant of reaction with temperature. If a graph is plotted between $\mathrm{lnK}$ vs $\frac{1}{\mathrm{T}}$ , the slope of the graph will be (K= rate constant, T= absolute temperature)

• A

  $\frac{{\mathrm{E}}_{\mathrm{a}}}{2.303\mathrm{R}}$

• B

  $\frac{{\mathrm{E}}_{\mathrm{a}}}{\mathrm{R}}$

• C

  $-\frac{{\mathrm{E}}_{\mathrm{a}}}{2.303\mathrm{R}}$

• D

  $-\frac{{\mathrm{E}}_{\mathrm{a}}}{\mathrm{R}}$
