Question 12
F

Hydrated copper(II) sulfate is heated and the forward reaction takes in energy. Water is then added to the anhydrous copper(II) sulfate that is formed. What happens to the temperature of the tube, and why?

[1]
A

It rises, because the reverse reaction is exothermic

B

It falls, because the reverse reaction is endothermic

C

It rises, because the reverse reaction is endothermic

D

It falls, because the reverse reaction is exothermic
