Energy is used to boil the liquid.

Δ

2

as written should be larger than

Δ

1

(i.e. when the gas is condensed energy is released).

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

Δ

2

>

Δ

1

. That is we get more energy out when the product is a liquid than when it is a gas.

Others may have a different take on this (and they certainly may have a better way of rationalizing the answer!).

Answer:

In this reaction no catalyst is used but

4hcl+o2=2cl2+2h2o in this reaction cucl2 is the catalyst
