Homework Help: Kp and Decomposition (Chemistry)

  1. Feb 7, 2010 #1
    For the reaction at 523K PCl5 (g) <-> PCl3 (g) + Cl2 (g) and Kp = 0.500

    What percentage of PCl5(g) will decompose if 0.100 atm of PCl5(g) is placed in a closed vessel at 523K?

    I am unsure of how to approach this problem, if anyone could give some insight I would greatly appreciate it.

    Look at your definition of Kp. All will become apparent.
