The special stability of chelates has to be explained with an example. Concept Introduction: Entropy means “randomness or disorderliness”. Entropy is a thermodynamic term deals with disorderliness in the system. It is denoted by ‘S’ and entropy change is denoted by Δ S . Increase in entropy indicates increase in disorderliness. The term free energy refers to available energy in the system to do work. Lesser the energy of the system more will be the stability of the system. It is denoted by ‘G’ and change in free energy is represented as Δ G . Enthalpy of the system refers to heat content of the system and it is denoted by ‘H’ . Change in enthalpy is denoted as Δ H . These three thermodynamic terms are related as, Δ G = Δ H-T Δ S

Interpretation Introduction

Interpretation:

The special stability of chelates has to be explained with an example.

Concept Introduction:

Entropy means “randomness or disorderliness”. Entropy is a thermodynamic term deals with disorderliness in the system. It is denoted by ‘S’ and entropy change is denoted by ΔS . Increase in entropy indicates increase in disorderliness.

The term free energy refers to available energy in the system to do work. Lesser the energy of the system more will be the stability of the system. It is denoted by ‘G’ and change in free energy is represented as ΔG.

Enthalpy of the system refers to heat content of the system and it is denoted by ‘H’. Change in enthalpy is denoted as ΔH.

These three thermodynamic terms are related as,

ΔG = ΔH-TΔS
