For the reaction I₂(s) + Cl₂(g) → 2 ICl(g) ΔH = 36 kJ and ΔS = 158.8 J/K at 25 °C. Calculate ΔG for the process at 25 °C. A) -11.3 kJ B) -4730 kJ C) -393 kJ D) 32 kJ E) 83.3 kJ

Question

Quizplus · Accepted Answer

ΔG can be calculated using the formula ΔG = ΔH - TΔS. Convert ΔS to kJ by dividing by 1000, then plug in the values: ΔG = 36 kJ - (298 K)(0.1588 kJ/K) = -11.3 kJ.
