Chapter 6, Problem 104CP

(a)

Interpretation Introduction

Interpretation:Value of $K$ is to be calculated.

  ${\text{SbCl}}_{\text{5}}\left(g\right)\rightleftharpoons {\text{SbCl}}_{\text{3}}\left(g\right)+{\text{Cl}}_2\left(g\right)$

Concept introduction: Chemical equilibrium is taken into consideration if rate of forward and backward reactions become equal. At this stage, both reactants and products have constant concentration. It can be studied in terms of pressure also. Equilibrium constant in pressure is denoted by $K_{\text{p}}$ .

Expression for ideal gas equation is as follows:

  $PV=nRT$

Where,

• $P$ is pressure of the gas.
• $V$ is volume of gas.
• $n$ denotes moles of gas.
• $R$ is gas constant.
• $T$ is temperature of gas.

Interpretation Introduction

Interpretation:Moles of ${\text{Cl}}_2$ to be added is to be determined.

  ${\text{SbCl}}_{\text{5}}\left(g\right)\rightleftharpoons {\text{SbCl}}_{\text{3}}\left(g\right)+{\text{Cl}}_2\left(g\right)$
