Chapter 22, Problem 22.48SP

Interpretation Introduction

Interpretation:

Some enzymes lose their activities under cold condition has to be explained.

Concept Introduction:

Enthalpy change is $\Delta H^0$ and entropy change is $\Delta S^0.$

Gibbs free energy change is $\Delta G^0.$ $\Delta H^0,\Delta S^0$ and $\Delta G^0.$ are related as,

    ${\text{ΔG}}^{\text{0}}{\text{=ΔH}}^{\text{0}}{\text{-TΔS}}^{\text{0}}$

Gibbs free energy change is denoted as ‘G’.  $\Delta G^0$  Refers to change in free energy.  $\Delta G°$ is defined as standard free energy change under standard conditions of $25°C$ temperature and $1\text{ atm}$ pressure.
