What is the ΔG for the forward reaction at 100°C? C₂H₄(g)+ H₂(g)⇌ C₂H₆(g);ΔH= -137.5 kJ;ΔS = -120.5 J/K

Quizplus · Accepted Answer

ΔG can be calculated using the formula ΔG = ΔH - TΔS. Convert temperature to Kelvin (100°C = 373 K) and ΔS to kJ (ΔS = -0.1205 kJ/K). ΔG = -137.5 kJ - (373 K * -0.1205 kJ/K) = -137.5 kJ + 44.9165 kJ = -92.5835 kJ, which is approximately -92.55 kJ.
