Chapter 21, Problem 60IAE

Interpretation Introduction

Interpretation:

To calculate ${\Delta }_{hydr}{S}^0$ and the trend in the ${\Delta }_{hydr}{S}^0$ values should be explained according to below data.

Concept introduction:

A process which happens without any outward intervention is recognized as the spontaneous

process. As per the 2^nd law of thermodynamics, that states the universe’s entropy rises for any spontaneous process.

A process which happens when pressure and temperature both are constant, the determination

of spontaneity can be done using Gibbs free energy: -

ΔG = ΔH − TΔS

Here, sign of ΔG is dependent on changes in entropy ΔS and enthalpy ΔH.
