Question 35

Multiple Choice

Use the following information to answer this question.
H2(g) + F2(g) \rightarrow 2 HF(g)   Δ\Delta G ° = -190 kJ/molrxn
H2(g) + Cl2(g) \rightarrow 2 HCl(g)   Δ\Delta G ° = -546 kJ/molrxn
H2(g) + Br2(g) \rightarrow 2 HBr(g)   Δ\Delta G ° = -106 kJ/molrxn
H2(g) + I2(g) \rightarrow 2 HI(g)   Δ\Delta G ° = 4 kJ/molrxn
