13.4 Exercise 25

Assume that the change in concentration of N₂O₄ is small enough to be neglected in the following problem.

(a) Calculate the equilibrium concentration of both species in 1.00 L of a solution prepared from 0.129 mol of N₂O₄ with chloroform as the solvent.

$\text{N}_{2} \text{O}_{4} \left(g\right) \rightleftharpoons 2 \text{NO}_{2} \left(g\right) K_{c} = 1.07 \times 10^{−5}$ in chloroform

(b) Confirm that the change is small enough to be neglected.
