Activation energy for the rever
se reaction=change in
enthalpy+activation energy of forward reaction.so
For enzyme catalyzed reaction
Activation energy for reverse reaction=22.7+25.2=47.9 kj/mole
Similiarly For acid catalyzed reaction
Activation energy for reverse reaction=55.5+57.9=113.4 kj/mole.
I hope u understand it.

The activation energy for the isomerization of cyclopropane to propene is 274 kJ/mol. By what factor does the rate of this reaction increase as the temperature rises from 257 to 280 degree C? The factor is the ratio of the rates. Since rate is directly proportional to rate constant, the factor is also ratio of rate constants Make sure your units are correct and cancel properly and use the correct expression: k= Ae^-E_a/RT A catalyst decreases the activation energy of...
