Chapter 16, Problem 16.59SP

Interpretation Introduction

Interpretation:

The effect of temperature of the surroundings on $\Delta S_{surr}$ has to be explained.

Concept Introduction:

• Second law of Thermodynamics is stated as follows,

“ In any spontaneous process Entropy of the Universe always increases.”

• Entropy of the universe is referred as total entropy which is the sum of entropy of the system and entropy of surroundings. 

$\Delta S_{total}=\Delta {\text{S}}_{sys}+\Delta S_{surr}$

Entropy of surroundings $\Delta S_{surr}$ is represented as,

$\Delta S_{surr}=\frac{-\Delta H}{T}$

Where $\Delta H=Enthalpy\text{ change, T = Temperature}\text{.}$
