Rate of a reaction increases by `10^6` times when a reaction is carried out in presence of enzyme catalyst at same temperature. Determine change in activation energy.

A hydrogenation reaction is carried out at 500 K. If the same reaction is carried out in the presence of catalyst at the same rate, the temperature required is 400 K. Activation energy of reaction if the catalyst lowers the activation energy barrier by 40 kJ/mol

A hydrogenation reaction is carried out at 500K.If the same reaction is carried out in the presence of a catalyst at the same rate temperature required is 400K. Calculate the activation energy of the reaction if the catalyst lowers the activation barrier by 20"kJ.mol"^(-1)
