An equilibrium mixture consists of 1 .00 mol of each species, in volume V and at temperature T . Three and one - third mol es of Cl2 (g) are now added , keeping P and T constant. Calculate the number of moles of Cl2 present when equilibrium is reestablished. Obtain also the ratio of the final to the original total volume.
