Question 1

Consider the following thermochemical equations:

​	ΔH° (kJ)
H2(g) +Cl2(g) →2HCl(g)	–184
H2(g) →2H(g)	432
Cl2(g) →2Cl(g)	239

Calculate the energy of an H-Cl bond using thesethermochemical equations.

◦ 855 kJ
◦ 244 kJ
◦ 487 kJ
◦ 92 kJ
◦ 428 kJ

Question 2

Consider the reaction:
              C₂H₅OH(l) + 3O₂(g) → 2CO₂(g) + 3H₂O(l); ΔH = –1.37 × 10³ kJ
Consider the following propositions:
I. The reaction is endothermic
II. The reaction is exothermic.
III. The enthalpy term would be different if the water formed was gaseous.
Which of these propositions is (are) true?

◦ I
◦ II
◦ III
◦ I, II
◦ II, III
