$PC{l}_5\left(g\right)$  is taken in a flask at 1.0atm, sealed and allowed to attain the 
following equilibrium: 
 $PC{l}_5\underset{ }{\overset{ }{\rightleftharpoons }}PC{l}_3+C{l}_2$
The equilibrium mixture was then allowed to pass through a pin hole and the gases coming out of pin hole initially, was collected, analyzed and mole fraction of  $C{l}_2$ was found to be 0.53. What is the value of $K_P$  for the dissociation of  $PC{l}_5\left(g\right)$? (in bar) (Rounded off to next nearest integer)
