Answer this asap 11.
The energies of activation for forward and reverse reaction
+ B 2ABare 180 kJ movi and 200 kJ movi
respectively. The presence of cataly'st lowers the activation
energy of both (forward and reverse) reactions by
100 kJ molA The enthalpy change of the reaction
(A, + B —i 2AB) in the presence of catalysi will be
(in kJ mol t).
Rate ofa reaction can be expressed by Arrhenius equation
_ E RT this eauation. E represents (2006)
