Equilibrium Test 10

Direction (Q. Nos. 1-8) This section contains 8 multiple choice questions. Each question has four
choices (a), (b), (c) and (d), out of which ONLY ONE option is correct.

Q. For the following equilibrium,

PCl₅(g)  PCl₃(g) + Cl₂ (g)

Vapour density is found to be 100 when 1 mole of PCI₅ is taken in 10 dm³ flask at 300 K. Thus, equilibrium pressure is

For the equilibrium, N₂O₄(g)  2NO₂(g)

here, d is experimental vapour density and D is theoretical vapour density. Thus, for the equilibrium 

In the following equilibrium at 400 K in 1 dm³ flask,

COCl₂ (g)CO(g) + Cl₂ (g),
ratio of theoretical and experimental vapour density is 1.4. Thus, equilibrium constant K_c is

A(g) is 100% converted into B according to the reaction,
A(g)  3b(g)
Value of   at this point is

In the dissociation of PCI₅(g)into PCI₃(g)and Cl₂(g), values of(1 + x)have been plotted versus D/d. Thus, correct graph is

CCI₄(g) dissociates 50% into gaseous free radicals at 1000 K and at equilibrium experimental vapour density is found to be 38.5. Thus, CCI₄(g) dissociates under the given conditions to

0.578 g N₂O₄(g) dissociates into 1dm³ flask at 308 K to give a pressure of 24.12 kPa.
N₂O₄ (g)  2NO₂(g)
Thus, degree of dissociation of N₂O₄ is 

SO₃(g)is partially dissociated into SO₂(g)and O₂(g) at 900K and 1 atm as: 

The density of the equilibrium mixture was found to be 0.866 gdm^-3. Thus, degree of dissociation of SO₃ (g) is
