Consider the following reaction:
PCl5(g)⇌PCl3(g)+Cl2(g)
1) Initially, 0.55 mol of PCl5 is placed in a
1.0 L flask. At equilibrium, there is
0.14 mol of PCl3 in the flask. What is the
equilibrium concentration of PCl5?
2) What is the equilibrium concentration
of Cl2? Express your answer to two significant figures
and include the appropriate units.
3) What is the numerical value of the equilibrium
constant, Kc, for the reaction? Express your answer using
two significant figures.
4) If 0.25 mol of Cl2 is added to the
equilibrium mixture, will the concentration of PCl5 increase
or decrease?
