Question

At temperature TK, PCI, Is 50% dissociated at an equilibrium pressure of 4 atm. At what pressure it wou
dissociate to the extent of 80% at the same temperature?
(1) 0.05 atm
(2) 0.60 atm
(3) 0.75 atm
(4) 2.50 atm​

Answer 1

Answer:

Explanation:

pcl5=pcl3+cl2

x           0     0

x-a        a      a

a=50/100 x

substitute it in 1/2x=4

x=8atm

a=80/100x

a=6.4

difference between 6.4 and 8 is 1.5

Answer 2

answer is 0.75atm

for the temprature 50 and 80
