Which outcome occurs when compressing dinitrogen tetroxide gas?

A)Rate of decomposition decreases.
B)Equilibrium shifts, favors colorless dimer.
C)Color intensity remains constant
D)Kinetic energy remains unchanged

💡 Explanation

Le Chatelier's principle favors fewer gas molecules when pressure increases, so the system shifts towards the colorless dimer. Equilibrium shifts, favoring condensation, because this produces nitrogen dioxide at higher proportions, therefore absorbance increases rather than decreases to maintain consistent conditions.
