Problem

Consider the reaction below, what is ΔG when the pressures of the gases are as follows at 25 °C?

H2 = 0.20 atm; Cl 2 = 0.30 atm; HCl = 0.90 atm. The value for ΔG° is −190 kJ/mol

                        H2(g) + Cl2(g) → 2 HCl(g)

A.  −190.0 kJ/mol

B.  6.4 kJ/mol

C.  45.5 J/mol

D.  183.5 kJ/mol

E.  −183.5 kJ/mol
