Chapter 4: Q-4-53P (page 235)
When ethene is treated in a calorimeter with H2and a Ptcatalyst, the heat of reaction is found to be -137kJ/mol(-32.7kcal/mol), and the reaction goes to completion. When the reaction takes place at 14000K, the equilibrium is found to be evenly balanced, with Keq=1. Compute the value of ΔSfor this reaction.
Short Answer
ΔS = -98J/mol.K
