Question

AB3 dissociated to form AB2 and B2 when the initial pressure of AB2 is 800 torr and the total pressure developed at eqilibrium is 900 torr.what is the fraction of AB3 dissociated more AB3 Could produced at equilibrium by

Answer 1

Answer:

AB2(g)+21B2(g)

When the initial pressure of AB3 is 800torr and the total pressure developed at equilibrium is 900 torr. What fraction of AB2(g) is dissociated?

A .

10%

B .

20%

C .

25%

D .

30%

ANSWER

AB3(g)⟶AB2(g)+21B2(g)aooa−aαaα2aα

Where α is the degree of dissociation.

a=800torr

a−aα+aα+2aα=900α=41

% dissociated =α×100=41×100=25%
