Calculate the equilibrium constant 2SO2(g]+O2(g]⇌2SO3(g]

Question

given equilibrium constant of SO2,O2,SO3 are 0.3m,0.14,1.45 respectively wt happens to the equilibrium constant a) if so2 is added b)if o2 is removed

Answer 1

K = (SO3)^2/(SO2)^2(O2)
You are given the concentrations of each (I assume that m stands for M). Just substitute and you get K.
What happens to the equilibrium constant if SO2 is added or O2 removed? Nothing happens. The CONCENTRATIONS will change but the K will not.
