APFIVE Equilibrium Position and the Magnitude of K
The reaction 2SO2(g) + O2(g) ⇌ 2SO3(g) has an equilibrium constant, K, of 4.2 × 10^24 at 25°C. If equimolar quantities of SO2(g) and O2(g) are combined in a sealed container, which of the following best describes the composition of the mixture at equilibrium?
A
A dynamic equilibrium with significant amounts of all species
B
Predominantly SO2 and O2 with trace amounts of SO3
C
Almost complete conversion to SO3
D
Approximately equal concentrations of all species
