Using the following thermochemical data:
2Ga(s) + 6HF(g) → 2GaF3(s) + 3H2(g)
ΔH° = –699.4 kJ/mol
2Ga(s) + 6HCl(g) → 2GaCl3(s) + 3H2(g)
ΔH° = –495.6 kJ/mol
calculate ΔH° for the following reaction:
GaF3(s) + 3HCl(g) → GaCl3(s) + 3HF(g)


◦ –1195.0 kJ/mol
◦ 203.8 kJ/mol
◦ 101.9 kJ/mol
◦ 407.6 kJ/mol
◦ –597.5 kJ/mol
