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
