InterviewSolution

1.	Assertion (A) : In the preparation of oxygen from KClO_(3),MnO_(2) acts as a positive catalyst. Reasson (R ) : MnO_(2) decreases the activation energy of the reaction
Answer» Both A and R are CORRECT is the correct explanation of A. Both A and R are correct and R is not the correct explanation of A. A is correct and R is WRONG A is wrong and R is correct. Solution :Positive CATALYST DECREASES the ACTIVATION energy of the reaction. Hence, the rate of reaction increases.
