If 20.00 mol of hydrogen gas completely reacted with 20.00 mol of chlorine gas
at constant pressure, releasing 3700 kJ of heat, which of the following
thermochemical equations is correct?
H2(g) + Cl2(g) => 2HCl (g); AH° = -185 kJ
H2(8) + Cl2(8) => 2HCl (g); AH° = +185 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = +370 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = -3700 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = -1850 kJ
