The equilibrium constant is equal to 5.00 at 1300 K for the reaction: If initial concentrations are [SO2] = 0.60 M, [O2] = 0.20 M, and [SO3] = 0.50 M, the system is: A. at equilibrium B. Need to know the volume of the container before deciding. C. not at equilibrium and will shift to the right to achieve an equilibrium state D. not at equilibrium and will shift to the left to achieve an equilibrium state E. not at equilibrium and will remain in an unequilibrium state 2 SO2(g) + O2(g) ⇌ 2 SO3(g)
