Two solids A and D dissociates into gaseous products as follows
A(s) 
B(g) + C (g) ; 
= 300 ;
D(s) 
E(g) + C (g) 
= 600
at 27ºC , then find the total pressure of the solid mixture.

CHECK THE SOLUTION.
(60 atm)
A(s) 
B(g) + C(g) 
= 300
– P 1 (P 1 +P 2 ) 
= P 1 (P 1 +P 2 )
D(s) 
E(g) + C(g) 
= 600
P 2 P 1 +P 2 
= P 2 (P 1 +P 2 )
= 
= 
= 
P 2 = 2P 1
= P 1 (P 1 +P 2 )
= P 1 (P 1 +2P 1 )
300 = P 1 (3P 1 )
P 1 2 = 100 (P 1 = 10)
P 2 = 20 atm
Now Total pressure
P B + P E + P C
(P 1 +P 2 ) + (P 1 +P 2 ) = (10 + 20) + (30) = 60 atm.
