A mixture of SO2, O2, and SO3 at 1000 K contains the gases at the following concentrations: [SO2] 5.0 x10-3 M [O2] 1.9 x10-3 M [SO3] 6.9 x 10-3 M Is the reaction at equilibrium? If not, which way will the reaction proceed to reach equilibrium? I know that Q=K K=1000 Kc=279 2 SO2(g) + O2(g) <---> 2 SO3(g)
