Dinitrogen tetroxide, $\text{N}_2\text{O}_4$, undergoes reversible decomposition. $\text{N}_2\text{O}_4 \rightleftharpoons 2\text{NO}_2 \qquad \Delta H = +58.0\,\text{kJ mol}^{-1}$ A mixture at equilibrium containing $\text{N}_2\text{O}_4$ and $\text{NO}_2$ gases is introduced into a closed container in standard conditions. $K_c = 1.15 \times 10^{-1}\,\text{mol dm}^{-3}$ The conditions are then altered. With the revised conditions, $K_c = 1.70 \times 10^{3}\,\text{mol dm}^{-3}$. Which change in conditions has taken place?
- AThe pressure increases.
- BThe pressure decreases.
- CThe temperature increases.
- DThe temperature decreases.
