Chapter 18, Problem 36QP

Interpretation Introduction

Interpretation:

To determine the signs of enthalpy and entropy for the reacting system. The temperature at which the denaturation becomes spontaneous is to be calculated.

Concept introduction:

The equation of Gibbs free energy is represented as:

$\text{Δ}G=\text{Δ}H-T\Delta S$

Here, $\text{Δ}G$ is theGibbs free energy, $\text{Δ}H$ is theenthalpy of the reaction, $T$ is thetemperature, and $\text{Δ}S$ is theentropy.

Gibbs free energy is zero when the system is at equilibrium.

For spontaneous reaction ΔG is negative.
