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
