Assertion(A): The catalyst can increase that rate constant to a large extent.
Reason(R): By using a suitable catalyst, we can increase the rate of reaction.

Consider the following graph

Choose the incorrect statement(s)

1.  Reaction is exothermic forward direction i.e., H = -ve

2.  Activation energy for forward reaction is x - y

3.  Using catalyst energy will decrease H value of the reaction

4.  All of these
