In the presence of an enzyme, the activation energy of a reaction

Increases

Decreases

Remains same

Cannot be predicted

Statement 1: Lower the activation energy, faster is the reaction. Statement 2 : Catalyst does not affect activation energy of the reaction.

Statement 1: is true, Statement 2 is true, and Statement 2 is a correct explanation of statement 1

Both statement are true but statement 2 is not a correct explanation for statement 1

Statement 1 is true and statement 2 is false

Statement 1 is false and Statement 2 is true

Assertion : If the activation energy of a reaction is zero , temperature will have no effect on the rate constant . Reason : Lower the activation energy , faster is the reaction .

If both assertion and reason are true and the reason is the correct explanation of the assertion .

If both assertion and reason are true but reason is not the correct explanation of the assertion

If assertion is true but reason is false .

If the assertion and reason both are false .
