Question 1

Determine the enthalpy change in the following equation:

2 NH3(g) → N2(g) + 3 H2(g)
Δf NH3(g) = -46.11 kJ/mol

◦ 92.22 kJ/mol
◦ 46.11 kJ/mol
◦ 5.42 kJ/mol
◦ -92.22 kJ/mol
◦ -46.11 kJ/mol

Question 2

Determine the enthalpy change in the following equation:

2/3 H2S(g) + O2(g) → 2/3 SO2(g) + 2/3 H2O(l)
Δf H2O(l) = -285.8 kJ/mol
Δf H2S(g) = -20.63 kJ/mol
Δf SO2(g) = -296.8 kJ/mol

◦ -562 kJ/mol
◦ -375 kJ/mol
◦ 375 kJ /mol
◦ -402 kJ/mol
◦ 402 kJ/mol
