This is quite a difficult question in that we have to make assumptions: I think the answer is
Explanation:
The difference between
Energy is used to boil the liquid.
Note that the fact that exothermic reactions (and this one certainly is) are written as NEGATIVE, is a distractor. Here, because the energy is listed as a product (and not as a separate thermoodynamic property), we should be able to say that
Others may have a different take on this (and they certainly may have a better way of rationalizing the answer!).
