Assertion (A) : A catalyst increases the rate of a reaction. Reason (R) : In presence of a catalyst, the activation energy of the reaction increases. The correct answer is
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of ( A )
- C(A) is true, but (R) is not true
- D(A) is not true, but (R) is true
Correct answer
C. (A) is true, but (R) is not true
Step-by-step solution
A catalyst increases the rate of reaction because in the presence of catalyst the activation energy of the reaction decreases.
