In collision theory according to arrhenius plot, intercept is equal to

The Arrhenius equation is, k=Ae^−Ea​/RT.
ln K=ln A−$\frac{{\mathrm{E}}_{\mathrm{a}}}{\mathrm{RT}}$

Comparing with equation y=m×x+c

Where, m=slope and c=intercept

Slope= $\frac{-{\mathrm{E}}_{\mathrm{a}}}{\mathrm{R}}$​​, Intercept=ln A
