♠Explain this statement(attached above) in brief♠

⟨Threshold Energy= Activation energy+ Energy of molecules⟩​

Answer 1

Explanation:

So, for the reaction to take place, activation energy is supplied to the molecules that don't have enough energy to reach the threshold energy that molecules need for the reaction to take place. Hence the activation energy is equal to the difference between the threshold energy and the normal energy of the reactants.

Answer 2

Answer:

I think first sentence is wrong. But second sentence is correct for sure

See the diagram in attachment and try to understand. :)

As ΔH is +ve, it is endothermic reaction.

[If we take the number of B as 5 and A is 3, then their difference is 2, which is positive. So ΔH is +ve]

Eₐ of reactants is more than Eₐ of products but threshold energy is same.

Eₙ(Normal energy or Energy of molecules) of products is higher than the reactants.

Hope it helps!
