F

When hydrated copper(II) sulfate is heated, the forward reaction takes in 78 kJ of energy for each mole of hydrated copper(II) sulfate that reacts.

hydrated copper(II) sulfate ⇌ \rightleftharpoons\,⇌ anhydrous copper(II) sulfate + water

a.

Name the type of energy change in the forward reaction.

[1]
b.

State the type of energy change in the reverse reaction and give the amount of energy transferred.

[2]
c.
