Question 1

Determine the enthalpy change in the following equation:

Cl2(g) + H2O(l) → 2 HCl(g) + 1/2 O2(g)
Δf H2O(l) = -285.8 kJ/mol
Δf HCl(g) = -92.31 kJ/mol

◦ 193.5 kJ/mol
◦ -470.4 kJ/mol
◦ 470.4 kJ/mol
◦ 101.2 kJ/mol
◦ -101.2 kJ/mol

Question 2

For a particular process that is carried out at constant pressure, q = 145 kJ and w = -35 kJ. Therefore:
◦ ΔU = 110 kJ and ΔH = 145 kJ
◦ ΔU = 145 kJ and ΔH = 110 kJ
◦ ΔU = 145 kJ and ΔH = 180 kJ
◦ ΔU = 180 kJ and ΔH = 145 kJ
