1.	At 25^(@)C , the activation energies for a reaction in absence and presence of a catalyst areE_(a) and (E_(a) -2) "kcal.mol"^(-1) , respectively . For the reaction , the reaction -rate and enthalpy change in absence of catalyst are r "mol.L"^(-1).s^(-1) and DeltaHk "cal.mol"^(-1) , respectively . which of the following would be true regarding the reaction when it is carried out in presence of a catalyst -
Answer» reaction -rate`= 14xxr "mol"^(-1).L.s^(-1)` reaction -rate`= 28xxr "mol"^(-1).L.s^(-1)` change in enthalpy`= DELTAH "kcal.mol"^(-1)` change in enthalpy `=(DeltaH)/(2)"kcal.mol"^(-1)` Answer :B::C
