# What is the slope of the straight line for the graph drawn between ln $k$ and $\large\frac{1}{T}$, where $k$ is the rate constant of a reaction at temperature T?

$\begin {array} {1 1} (1)\;\frac{-E_{\alpha}}{2.303R} & \quad (2)\;\frac{-E_{\alpha}}{R} \\ (3)\;\frac{E_{\alpha}}{R} & \quad (4)\;\frac{R}{E_{\alpha}} \end {array}$

$(2)\;\frac{-E_{\alpha}}{R}$
