Chapter 15, Problem 15.105SP

Interpretation Introduction

(a)

Interpretation:

The value of K_c at 500 K needs to be determined.

Concept introduction:

The relation between equilibrium constant with respect to concentration and pressure can be represented as follows:

${\text{K}}_{\text{P}}{\text{=K}}_{\text{c}}\text{×}{\left(\text{RT}\right)}^{\text{n}}$

Here, n is change in number of moles of gases that is product-reactant, R is Universal gas constant and T is temperature.

Interpretation Introduction

(b)

Interpretation:

The molar concentrations of products and reactants are to be determined.

Concept introduction:

For the equilibrium reaction, the expression for the equilibrium constant is the ratio of concentration of product to reactant raised to their stoichiometric coefficients.

Interpretation Introduction

(c)

Interpretation:

Theequilibrium partial pressure of tert-butyl chloride, isobutylene, and hydrochloric acid needs to be determined.

Concept introduction:

For the equilibrium reaction, the expression for the equilibrium constant is the ratio of concentration of product to reactant raised to their stoichiometric coefficients.

It can also be written in the form of partial pressure of the species at equilibrium. In this case, it is denoted by symbol $k_p$. It is equal to the ratio of partial pressure of product to reactant raised to their respective stochiometric coefficients.
