Question
The reaction A(g) + B(g) ⇋ C(g) + D(g) is studied in a one litre vessel at 250oC. The initial concentration of A was 3n and that of B was n. When equilibrium was attained, equilibrium concentration of C was found to the equal to the equilibrium concentration of B. What is the concentration of D at equilibrium?
Options
A.n/2
B.(3n - 1/2)
C.(n - n/3)
D.n
Solution
A + B ⇋ C + D
3n n 0 0 t = 0
(3n-x) (n-x) x x t = teq.
(n-x) = x
n = 2x x = n/2
3n n 0 0 t = 0
(3n-x) (n-x) x x t = teq.
(n-x) = x
n = 2x x = n/2
