Chapter 3, Problem 12Q

A.

Summary Introduction

To calculate: The equilibrium constant for the reaction $\text{A}\text{+}\text{B}\leftrightarrow \text{AB}$.

Introduction: Equilibrium constant is defined as the ratio of amount of products over the amount of reactants in equilibrium. It is denoted as “K”.

B.

Summary Introduction

To calculate: The equilibrium constant if A, B and AB were each present in equilibrium.

Introduction: Equilibrium constant is defined as the ratio of amount of products over the amount of reactants in equilibrium. It is denoted as “K”.

C.

Summary Introduction

To calculate: The extra hydrogen bonds required to hold A and B together at lower concentration so that a similar proportion of molecules are found in the AB complex.

Introduction: In a chemical reaction, reactants are converted into products. Concentration of reactants affects the rate of the reaction. The higher the concentration of reactants, the more rapid will be the collision between them. This will result in more product formation. The formation of products from reactants is called a forward reaction. When the products’ concentration is increased, they frequently collide and the reaction results in a reverse direction. The formation of reactants from products is called a reverse reaction. The forward reaction and reverse reaction attain a steady point of state called as a chemical equilibrium.
