Question
Question: A catalyst increases rate of reaction by :...
A catalyst increases rate of reaction by :
A
Decreasing enthalpy
B
Decreasing internal energy
C
Decreasing activation energy
D
Increasing activation energy
Answer
Decreasing activation energy
Explanation
Solution
Catalyst provides new path to the chemical reaction which has lower value of activation energy. Reactant and product with not be affected, so there will not be any change in state parameter like enthalpy and internal energy.
