Final answer:
The equilibrium constant, Keq, measures the ratio of product concentrations to reactant concentrations at equilibrium. The Keq value for the reaction N₂O₄(g) ⇌ 2NO₂(g) can be determined using experimental data provided. At 298 K, the Keq is 5.9 × 10ˉ³, and at 398 K, the Keq is 1.3 × 10ˉ
Step-by-step explanation:
The equilibrium constant, Keq, represents the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. To determine the Keq value, we can use the equation:
Keq = [NO2]² / [N2O4]
Using the given experimental data, we can calculate the Keq value at two different temperatures:
Temperature = 298 K, Keq = 5.9 × 10ˉ³
Temperature = 398 K, Keq = 1.3 × 10ˉ
