Question
3·00 mol of PCl5 kept in 1L closed reaction vessel was allowed to attain equilibrium at 380K. Calculate the composition of the mixture at equilibrium, Kc = 1·80.
Solution
Let x mol of PCl5 be dissociated.
The reaction is
Initial conc. 3.0 0 0
At eqm. 3 - x x x
Applying the law of chemical equilibrium
...(1)
Putting the values in expression (1), we have
