equilibrium constant (Kp)
posted by k on .
What is the equilibrium constant "Kp" at 200 C for the reaction below:
P4(s) + 6 Cl2(g) --><-- 4 PCL3(l)
Given the following at 200 C
P4(s)+ 10 Cl2(g) --><-- 4 PCl5(s) Kc=8.12
PCl3(l)+ Cl2(g) --><-- PCl5(s) Kc=0.771
not sure what to do.
I know Kp=Kc(RT)^(delta n)
but the fact that they gave me two Kc values is confusing. Am I supposed to use those to somehow find the concentrations of the gaseous compounds?
Also, is "delta n" just the "final n" - "initial n" for the first reaction given (i.e. -3 or -6 depending on whether or not non-gasses count for "delta n" or not)?
Thank you in advance
