Chemical Equili...

The equilibrium, is attained at 25^oC in a closed container and an inert gas He is introduced. Choose the correct statement.

A vessel at 1000 K contains CO₂ with a pressure of 0.5 atm. Some of the CO₂ is converted into CO on the addition of graphite. If the total pressure at equilibrium is 0.8 atm, the value of K_P is:

40% of a mixture of 0.2 mol of N₂ and 0.6 mol of H₂ react to give NH₃ according to the equation, N₂(g) + 3H₂(g) ⇌ 2NH₃(g), at constant temperature and pressure. Then the ratio of the final volume to the initial volume of gases are

One mole of ethanol is treated with one mole of ethanoic acid at 25°C. One-fourth of the acid changes into ester at equilibrium. The equilibrium constant for the reaction will be

One mole of N₂O₄(g) at 300 K is kept in a closed container under one atmosphere. It is heated to 600 K when N₂O₄ (g) 23 decomposes to NO₂(g). If the resultant pressure is 2.4 atm, the percentage dissociation by mass of N₂O₄ (g) is

K for the synthesis of HI(g) is 50. The degree of dissociation of HI is

For the reaction PCl₃ (g) + Cl₂ (g) ⇌ PCl₅ (g), the value of Kp at 250°C is 0.61 atm^–1. The value of K_c at this temperature will be

In the reaction A₂(g) + 4B₂(g) ⇌ 2AB₄(g) , ∆H > 0. The decomposition of AB₄ (g) will be favoured at

In a system, A (s) ⇌ 2B (g) + 3C (g)

If the conc. of C at equilibrium is increased by a factor of 2, it will cause the equilibrium concentration of B to change to

For the following three reactions (i), (ii) and (iii), equilibrium constants are given

(i) CO (g) + H₂O (g) ⇌ CO₂ (g) + H₂ (g) ; K₁

(ii) CH₄ (g) + H₂O (g) ​​​​​​​⇌ CO (g) + 3H₂ (g) ; K₂

(iii) CH₄ (g) + 2H₂O (g) ​​​​​​​⇌ CO₂ (g) + 4H₂ (g) ; K₃

What is the relation between equilibrium constants of the three reactions?
