A reaction is catalysed by ‘X ’. Here ‘X ’.
A
Decreases the rate constant of reaction
B
Does not affect the equilibrium constant of reaction
C
Decreases the enthalpy of reaction
D
Decreases the activation energy
Answer
Decreases the activation energy
Explanation
Solution
Catalyst reduce the activation energy for reaction and thus increase the rate of reaction.
