    At 350K, PCl5 dissociates into PCl3 and Cl2 and an equilibrium is reached.

    Write balanced equation:
    My answer =
    PCl5 <--> PCl3 + Cl2

    equilibrium mixture contained 2.50*10^-2 moldm^-3 Cl2 and 2.50*10^-2 moldm^-3 PCl3.

    Find the equilibrium concentration of PCl5 if Kc is 5.67 * 10^-3 moldm^-3 at 350K

    My answer =

    5.67*10^-3 = (2.50*10^-2) * (2.50*10^-2)

    = 0.110moldm^-3
