The equilibrium constant is equal to 5.00 L mol-1 at 1300 K for the reaction:
2SO2(g) + O2(g) ⇌ 2SO3(g)
If initial concentrations are [SO2] = 6.00 mol L-1, [O2] = 0.45 mol L-1, and [SO3] = 9.00 mol L-1, the system is
◦ not at equilibrium and will shift to the left to achieve an equilibrium state.
◦ not at equilibrium and will remain in an unequilibrated state.
◦ not at equilibrium and will shift to the right to achieve an equilibrium state.
◦ at equilibrium.
