if a given quantity of phosphorus pentachloride is heated at 250o C and allowed to come to equilibrium at atmospheric pressure it is found to be dissociated to the extent of 80% into phosphouroustri chloride and chlorine. If now, the pressure on this mixture is increased so that finally the equilibrium mixture occupies only one half of its original volume (temperature maintained costant).Submit your detailed Question here...

Full question::::if a given quantity of phosphorus pentachloride was heated to 250 degree Celsius and allowed to come to equilibrium at atmospheric pressure it is found to be dissociated to the extent of 80% into Phosphorus trichloride and chlorine if now the pressure on this mixture is increased so that final equilibrium mixture occupy only one half of its original volume temperature maintained constant .a) what will be the percentage dissociation at the new pressure?b) what would be the effect of adding helium gas keeping the volume fixed at the V/2?😎
