Q.
$E_{f} =$ activation energy of forward reaction
$E_{b} =$ activation energy of backward reaction
$E_{t} =$ threshold energy
In a reaction, $A + B \to C$ is exothermic to the extent of $30 k J / m o l$ and the activation energy of the forward reaction is $249 k J / m o l$ , then the activation energy of reverse reaction (in $k J / m o l$ ) is
