In the equilibrium described in Example 15-12, the percent dissociation of N₂O₄ can be expressed as

What must be the total pressure of the gaseous mixture if N₂O₄(g) is to be 10.0% dissociated at 298 K?

(for pressures in atmospheres).

Example 15-12

A 0.0240 mol sample of N₂O₄(g) is allowed to come to equilibrium with NO₂(g) in a 0.372 L flask at 25 °C. Calculate the amount of N₂O₄ present at equilibrium (Fig. 15-9).
