6.1 Introduction

In Chapter 4, we discussed mixtures of non-reactive gases. The special feature of such mixtures is that the chemical composition does not change during a process. But in many mixtures, the constituents react with each other, and therefore, the chemical composition is changed after the completion of the process. Some reactions take place in one direction only, and are called irreversible reactions, whereas the others take place in both the directions. That is, the products combine to form the reactants back. Such reactions ...
