“10th Class Chemistry Chapter 9 Quiz: Chemical Equilibrium” discusses the state of dynamic balance in chemical reactions and the laws governing it. This chapter is very important for MDCAT students because it gives the basis for understanding reversible reactions, reaction rates, and factors affecting equilibrium—the most important area that can be tested in competitive exams. Our MDCAT Quiz for this chapter provides a strong platform to practice these concepts effectively.
The chapter introduces the student to chemical equilibrium, bringing forth the concept of reversible reactions where the rate of the forward reaction equals the rate of the reverse reaction. Students will learn about the Law of Mass Action and how it is used in obtaining the equilibrium constant (Kc), which is a measure of the position of equilibrium. The chapter discusses factors that disturb equilibria, such as temperature, pressure, and concentration, in relation to Le Chatelier’s Principle, which predicts the response of systems to disturbances. Also included is the role of catalysts in equilibrium and the distinction between homogeneous and heterogeneous equilibria. The chapter provides examples of the industrial applications of chemical equilibrium, including the Haber process for the production of ammonia.
