A Chemistry student is trying to determine the effect of changing the volume on the equilibrium position of a chemical reaction at constant temperature. If the reaction is initially in equilibrium in a 1 L container with a concentration of [X] = 0.10 M and [Y] = 0.20 M, and then the volume is decreased to 0.4 L, what will be the new equilibrium concentrations of X and Y at the new volume?
