Problem
A sealed 1.0L vessel at 1000K contains the gases involved in the reaction
2 SO2(g)+ O2(g)⇌2 SO3(g)
At this temperature, Kc=4.0. A particulate-level snapshot shows 8 particles of SO2, 6 particles of O2, and 4 particles of SO3.
Calculate Qc using the particle counts and indicate whether the net reaction will proceed toward reactants, toward products, or is already at equilibrium.
