Interpretation Introduction

Interpretation: The value of $K_{\text{c}}$ for the two individual reactions is given. The value of $K_{\text{c}}$ for a net reaction obtained by the operations of the two individual reactions is to be calculated.

Concept introduction: The value of $K_{\text{c}}$ for the two addition reaction is calculated as,

$K_{\text{c}}{}_{{}_{\text{net}}}=K_{\text{c}}{}_{{}_1}\times K_{\text{c}}{}_{{}_2}$

The value of $K_{\text{c}}$ of decomposition is calculated by the formula,

$K_{\text{c}}\text{of}\text{decomposition}=\frac{1}{K_{\text{c}}\text{of}\text{formation}}$

The value of $K_{\text{c}}$ of a reaction forming the two different numbers of moles of product is calculated as,

${\left(K_{\text{c}}{}_{{}_1}\right)}^{n_2}={\left(K_{\text{c}}{}_{{}_2}\right)}^{n_1}$

Where, $n_1$ and $n_2$ represents the number of moles of product formed in the two reaction.

To determine: The value of $K_{\text{c}}$ for a net reaction obtained by the operations of the two individual reactions.
