Which of the following is correct for the reaction ?
N₂ (g) + 3H₂ (g) ⇌ 2 NH₃ (g)

For the reaction,
2NO₂ (g) ⇌ 2NO (g) + O₂ (g)
(K_C = 1.8 × 10^-6 at 184^o C)
(R = 0.00831 KJ/mol K)
where K_P and K_C are compared at 184^o C, it is found that

An amount of solid NH₄HS is placed in a flask already containing ammonia gas at a certain temperature and 0.50 atm pressure. Ammonium hydrogen sulphide decomposes to yield NH₃ and H₂S gases in the flask. When the decomposition reaction reaches equilibrium, the total pressure in the flask rises to 0.84 atm. The equilibrium constant for NH₄HS decomposition at this temperature is

In which of the following reactions is K_P < K_C ?

The change in pressure will not effect the equilibrium constant for

For a reaction H₂ + I₂ ⇌ 2HI at 721K, the value of equilibrium constant is 50. If 0.5 mole each of H₂ and I₂ is added to the system, then the value of equilibrium constant will be

If in the reaction N₂O₄ ⇌ 2 NO₂, x is that part of N₂O₄ which dissociates, then the number of molecules at equilibrium will be

At 550 K, the value of K_C for the following reaction is 10⁴ mol^-1 L
X (g) + Y (g) ⇌ Z (g)
At equilibrium, it was observed that
[X] = 1/2 [Y] = 1/2 [Z]
What is the value (in mol L^-1) of [Z] at equilibrium ?

2Ag₂ O (s) ⇌ 4 Ag (s) + O₂ (g)
Partial pressure of O₂ in the above reaction is

In the reaction at constant volume
C (s) + CO₂ (g) ⇌ 2CO (g)
Argon gas is added which does not take part in the reaction, choose the correct statement.
