Interpretation Introduction

Interpretation: The condition needs to be determined at which $\text{dA}\le \text{0}$ defines the spontaneity of a process.

Concept Introduction: A reversible chemical reaction can move in either forward or backward direction. The stage of a reversible reaction at which the rate of forward and backward reaction become equal to each other is called an equilibrium stage. The equilibrium constant for a reaction is the ratio of the equilibrium concentration of the product and reactant. If the reaction is given in the gaseous state, then the equilibrium pressure must be considered.
