The Keq is 0.0420 for the equilibrium reaction PCl4 (g) PCl3 (g) + Cl2 (g). Determine the equilibrium concentrations of all the species if the initial concentration of PCl5 is 0.0500M. Will mark as brainliest

0.02M

1 Answer. The equilibrium concentrations are [PCl3]=0.280M , [Cl2]=0.380M , [PCl5]=0.02M

Explanation:

Amount of Cl2(g) increases Reason: As PCl3(g) is removed/concentration decreased, the equilibrium will shift to oppose the change, i.e. increase the concentration of PCl3(g). This will favour the forward reaction, producing more Cl2.
