For a particular reaction, the change in enthalpy is −9kJmole and the activation energy is 13kJmole. The enthalpy change (ΔH) and activation energy (Ea) for the catalyzed reaction could be which of the following?
Select the correct answer below:
A)−9kJmole,5kJmole
B)−9kJmole,19kJmole
C)−14kJmole,5kJmole
D)−14kJmole,−13kJmole
The use of catalyst in a reaction, does not change the enthalpy of reaction but it decreases the activation energy. So the correct answer is A, where the enthalpy of reaction is -9kJmole and activation energy decreases from 13 to 5 kJmole.
