Question

Assuming the volume is 1L, calculate the equilibrium constant, Kc, for the reaction. Use numbers of particles in place of moles in the molarity formula.

Answer 1

there's the picture that goes with the problem

Answer 2

red = X = 2 molecules
blue = Y = 2 molecules
YX = 4 molecules

2X + Y2 -> 2XY

Kc=[products]/[reactants]= [XY]^2/([X]^2[Y2]) = 4^2/((2^2)(2))= 2
