Question
An uncatalyzed reaction has an activation energy Ea = 50 kJ mol-1 and an enthalpy change ∆H° = –10 kJ mol-1. In the presence of a catalyst, what might these values become?
A.✓ Correct
Ea = 30 kJ mol-1, ∆H° = –10 kJ mol-1
B.
Ea = 50 kJ mol-1, ∆H° = –15 kJ mol-1
C.
Ea = 60 kJ mol-1, ∆H° = –20 kJ mol-1
D.
Ea = –10 kJ mol-1, ∆H° = 50 kJ mol-1
