For the reaction:

PCl<sub>3</sub> + Cl<sub>2</sub> <>PCl<sub>5</sub>

The equilibrium constant at 250 degrees celsius is 23.8 (mol/L)<sup>-1</sup>. Calculate the equilibrium concentration of chlorine needed to make the equilibrium value of the ratio [PCl<sub>5</sub>]/[PCl<sub>3</sub>] equal to 2.

products on reactants so [pcl5]/([pcl3]*[cl2]) since we know pcl5/pcl3 is 2 therfore 2/[cl2] = 23.8 therefore cl2 = 2/23.8.

is that rite??
