At a certain temperature, the equilibrium constant Kc is 0.154
for the reaction
2 SO2(g) + O2(g) ⇀↽ 2 SO3(g)
What concentration of SO3 would be in equilibrium with 0.250
moles of SO2 and 0.541 moles of O2 in a 1.00 liter container at
this temperature? Note: These latter moles are the equilibrium
values. Answer in units of M.
