Question

The energy diagram shows the changes in energy during a chemical reaction.

Answer 1

There is no diagram attached but there are some ways by which you can find it too easily by yourself

Usually energy diagram uses ∆H .

So

• If ∆H is +ve means reaction is exothermic and energy is released
• If ∆H is -ve means reaction is endothermic and energy is absorbed

So observe∆H whether it. is decreasing or increasing ,

• If increasing then energy is being released and vice versa
