Calculate the standard enthalpy of formation of Cl-(aq), given the following thermochemical data at 1 atm, and knowing that the standard enthalpies of formation of H2(g) and H+(aq) are both zero.

HCl(g) → H+(aq) + Cl-(aq) ΔrH° = -75.15 kJ/mol
H2(g) + Cl2(g) → 2HCl(g)  ΔrH° = -184.62 kJ/mol

◦ -167.46 kJ/mol
◦ +109.47 kJ/mol
◦ -17.16 kJ/mol
◦ +34.32 kJ/mol
◦ + 167 kJ ?mol
