Question:medium
The rate constant of a reaction at 500 K is 0.02 and it increased to 0.07 at 700 K. The \(E_a\) value of the reaction is about [Given: \(R = 8.3 \, J\,K^{-1}\,mol^{-1}\) and \(\log(7/2) = 0.544\)].

Show Hint
Always ensure units for $R$ and $E_a$ (Joules vs KiloJoules) are consistent.
