Expert Answer:

p = i CRT
Calculation of Van't Hoff factor
            K3[ Fe(CN) 6]                  3 K+   +   [ Fe(CN) 6]3-                             
                  1                                     0             0
                1-α                                  3α             α
                           i =    1+ 3α /1 = 1+ 3x0.70 / 1= 3.10
                          
                                           p= i CRT

                                           p = 3.10 x 2 x 0.0821 x 300= 152.70 atm
