Question

When ethane is reacted in a calorimeter with H2 and a Pt catalyst, the enthalpy of the reaction was found to be -137 kJ/mol, and the reaction goes to completion. When the reaction takes place at 750 K, the entropy (ΔS) was measured to be 500 J/mol K. CH2=CH2 + H2 —Pt→ CH3-CH3 ΔH = -137 kJ/mol. Calculate the ΔG for the reaction (Hint: ΔG = ΔH - TΔS). Indicate whether or not the reaction is spontaneous.
