For a certain reaction consider the plot of \( \ell \mathrm{n} \mathrm{k} \) versus \( 1 / \mathrm{T} \) given in the figure. If the rate constant of this
\( \mathrm{P} \) reaction at \( 400 \mathrm{~K} \) is \( 10^{-5} \mathrm{~s}^{-1} \), then the rate constant at

W \( 500 \mathrm{~K} \) is :

(1) \( 10^{-6} \mathrm{~s}^{-1} \)
(2) \( 2 \times 10^{-4} \mathrm{~s}^{-1} \)
(3) \( 10^{-4} \mathrm{~s}^{-1} \)
(4) \( 4 \times 10^{-4} \mathrm{~s}^{-1} \)
