question 114

Multiple Choice

In a certain experiment,0.7000 mol of hydrogen gas reacted with 0.7000 mol of solid iodine at a constant 1 atm pressure,producing 1.4000 mol of solid hydrogen iodide and absorbing 36.9 kJ of heat in the process.Which of the following thermochemical equations correctly describes this experiment?

• A)H2(g)+ I2(s)→ 2HI(s); ΔH° = -52.72 kJ
• B)H₂(g)+ I₂(s)→ 2HI(s); ΔH° = 36.9 kJ
• C)H₂(g)+ I₂(s)→ 2HI(s); ΔH° = -36.9 kJ
• D)H₂(g)+ I₂(s)→ 2HI(s); ΔH° = 73.8 kJ
• E)H₂(g)+ I₂(s)→ 2HI(s); ΔH° = 52.72 kJ
