One mole of N2 and 3 moles of PCl5 are placed in a 100 litre vessel heated to 227ºC. The equilibrium pressure is 2.05 atm. Assuming ideal behaviour, calculate degree of dissociation of PCl5 and KP

```							Write the eqn. first,PCl5 ------->   PCl3   +  Cl2Use ideal gas eqn. to get the value of n .i.e moles and use concenrtrn for findoong Kpinstead of using partial pressure.Kp  = pcl3*cl2/pcl5
