Chapter 17, Problem 17.100SP

Interpretation Introduction

Interpretation:

${\text{ΔG}}^{\text{0}}$ of the reaction by using standard thermodynamic values should be determined and whether the reaction is spontaneous or not at ${\text{25}}^{\text{0}}\text{C}$ should be identified. Effect of increase in temperature on spontaneity of reaction and temperature at which reaction will become nonspontaneous should be determined.

Concept introduction:

1. The free energy change can be obtained from enthalpy and entropy at a given temperature.
2. The reaction is spontaneous if the free energy change is less than zero.

Given:${\text{CH}}_{\text{2}}{\text{=CH}}_{\text{2}}{\text{(g)+H}}_{\text{2}}\text{O (l)}\to {\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH(l)}$
