Question 1

Calculate the standard enthalpy change for the reaction
4A + 2B → 2AB + A2
Given:
2A + B → A2B
ΔH° = – 25.0 kJ/mol
2A2B → 2AB + A2
ΔH° = 35.0 kJ/mol
 

◦ – 95.0 kJ/mol
◦ – 60.0 kJ/mol
◦ – 15.0 kJ/mol
◦ 10.0 kJ/mol
◦ 45.0 kJ/mol

Question 2

Calculate the standard enthalpy of formation of liquid methanol, CH3OH(l), using the following information:
C(graph) + O2→ CO2(g)
ΔH° = –393.5 kJ/mol
H2(g) + (1/2)O2→ H2O(l)
ΔH° = –285.8 kJ/mol
CH3OH(l) + (3/2)O2(g) → CO2(g) + 2H2O(l)
ΔH° = –726.4 kJ/mol
 

◦ –1,691.5 kJ/mol
◦ –238.7 kJ/mol
◦ –47.1 kJ/mol
◦ 47.1 kJ/mol
◦ 1691.5 kJ/mol
