Question 1

Given  2Al(s) + (3/2)O2(g) → Al2O3(s),  ΔH°f = –1,670 kJ/mol for Al2O3 (s).
Determine ΔH° for the reaction 2Al2O3(s) → 4Al(s) + 3O2(g).
◦ –3,340 kJ/mol
◦ –1,670 kJ/mol
◦ –835 kJ/mol
◦ 1,670 kJ/mol
◦ 3,340 kJ/mol

Question 2

Given H2(g) + (1/2)O2(g) → H2O(l), ΔH° = –286 kJ/mol, determine the standard enthalpy change for the reaction 2H2O(l) → 2H2(g) + O2(g).
◦ ΔH° = –286 kJ/mol
◦ ΔH° = +286 kJ/mol
◦ ΔH° = –572 kJ/mol
◦ ΔH° = +572 kJ/mol
◦ ΔH° = –143 kJ/mol
