In a Certain Experiment,0

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
