Chapter 15, Problem 52GQ

Interpretation Introduction

Interpretation:

The total pressure for the reaction when decomposition of ${\text{COCl}}_{\text{2}}$ at equilibrium has to be determined

Concept Introduction:

Equilibrium constant in terms of concentration${\text{[K}}_{\text{c}}\text{]}$: Equilibrium constant can be expressed in terms of concentration.

$\begin{array}{l}\text{aA}{}_{\text{(g)}}\text{+}{\text{bB}}_{\text{(g)}}\rightleftarrows \text{cC}{}_{\text{(g)}}\text{+}\text{dD}{}_{\text{(g)}}\\ {\text{K}}_{\text{c}}\text{=}\frac{{\text{K}}_{\text{C}}{}^{\text{c}}\text{×}{\text{K}}_{\text{D}}{}^{\text{d}}}{{\text{K}}_{\text{A}}{}^{\text{a}}\text{×}{\text{K}}_{\text{B}}{}^{\text{b}}}\end{array}$

Molarity: It is the number of moles of substance present in a solution of litre.

Molarity $\text{=}\frac{\text{Number}\text{of}\text{moles}\text{of}\text{solute}}{\text{Volume}\text{of}\text{solution}\text{(L)}}$

Ideal gas equation:

$\begin{array}{l}\text{PV}\text{=}\text{nRT}\\ \text{P}\text{-}\text{Pressure}\\ \text{V}\text{-}\text{Volume}\\ \text{R}\text{-}\text{Universal}\text{gas}\text{constant}\\ \text{T}\text{-}\text{Temperature}\\ \text{n}\text{-}\text{number}\text{of}\text{moles}\end{array}$
