Chapter 15, Problem 86IAE

Interpretation Introduction

Interpretation:

Apparent molar mass of the gaseous mixture that results when COCl₂(g) is allowed to dissociate at ${395}^{0}C$ and a total pressure of $3.00\text{ atm}$ should be determined

Concept introduction:

Equilibrium constant in terms of partial pressures is the ratio between the partial pressures of products and reactants of a reversible reaction. Partial pressures are raised to the power of coefficient in the balanced equation.

$\begin{array}{l}\text{a A(g) + b B(g) }\rightleftharpoons \text{ c C(g) + d D(g)}\\ K_p=\frac{P_C{}^c\times P_D{}^d}{P_A{}^a\times P_B{}^b}\end{array}$
