In an experiment at 240 degrees celcius, it was found that for the reaction:
PCl3(g) + Cl2(g) <---> PCl5(g)
a) Calculate Kc for the reaction at this temperature.
b) if the volume of the reaction vessel is halved, calculate the new concentrations once equilibrium is re-established.
Work:
a) Kc=[.1]/([.1][.1])
Kc=10
b) 10=[.1/2]/(
10=[.05]/X^2
10X^2=[.05]
x^2=[.05]
x=.071
therefore the new concentrations are: PCl3=.071 | Cl2=.071 | PCl5= .5
is this correct?

...it was found that PCl3, PCl5 and Cl2 were all 10% v/v and the rest were inerts. :) Guessing!

umm, so is my work correct?

OOOH SOORRRRYYYY I FORGOT TO INCLUDE A PART!
QUESTION:
In an experiment at 240 degrees celcius, it was found that for the reaction:
PCl3(g) + Cl2(g) <---> PCl5(g)
equilibrium concentrations werer 0.100 mol/L PCl5.
a) Calculate Kc for the reaction at this temperature.
b) if the volume of the reaction vessel is halved, calculate the new concentrations once equilibrium is re-established.
