Chapter 15.3, Problem 4PE

Interpretation Introduction

Interpretation: The value of $K_{\text{P}}$ for the reaction between ${\text{N}}_{\text{2}}$ and ${\text{H}}_{\text{2}}$ at $3\text{0}{}^{\text{o}}\text{C}$ is to be calculated.

Concept introduction: The value of $K_{\text{P}}$ is calculated by the formula,

$K_{\text{P}}=K_{\text{C}}{\left(\text{R}T\right)}^{\Delta n}$

Where,

• $K_{\text{P}}$ is the equilibrium constant for partial pressure.
• $K_{\text{C}}$ s the equilibrium constant for concentration.
• Universal gas constant, $\text{R}=\text{0}\text{.082}\text{L}\text{.atm}/\text{mol}\text{.K}$.
• $\text{T}$ is the temperature.
• $\Delta n$ is the change in the number of moles and reactant between the product and reactant sides of the balanced chemical equation.

To determine: The value of $K_{\text{P}}$ for the reaction between ${\text{N}}_{\text{2}}$ and ${\text{H}}_{\text{2}}$ at $3\text{0}{}^{\text{o}}\text{C}$.
