For a particular gas phase reaction: A2 + B2  <--->  2 AB, the equilibrium concentrations are 0.206 M, 0.305 M, and 0.184 M, for A2, B2, and AB respectively. If 0.040 moles of AB is added to exactly 1 liter of the equilibrium mixture, determine the new equilibrium concentrations of A2, B2 and AB. Assume that the volume change can be ignored and that the temperature remains fixed. Show all your work.
