About this simulation

Investigate N₂O₄ ⇌ 2NO₂. Change temperature, container volume and initial amounts; compare reaction quotient Q with equilibrium constant K.

What students can explore

Predict whether heating or compressing the mixture produces more brown NO₂.

Learning objectives

1Predict whether heating or compressing the mixture produces more brown NO₂.

Questions teachers ask

What assumptions does this simulation use?

Ideal-gas concentration model. Kc = 0.006 at 298 K and ΔH = +57.2 kJ/mol. Equilibrium composition is solved numerically; displayed particles represent relative amounts.
