Chemical Equili...

The following question has four choices out of which ONLY ONE is correct.
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 

H₂O(l) ⇌ H₂O (vap). This equation best illustrates the

The mass of a gas dissolved in a given mass of a solvent at any temperature is proportional to the pressure of the gas above the solvent.

The Bronsted acid which gives the weakest conjugate base is

In the dynamic equilibrium stage, one of the following events take place. Choose the right one.

The dynamic nature of chemical equilibrium can be demonstrated in the synthesis of ammonia by Haber.s process. Choose the appropriate option given below

The factor that does not affect the state of equilibrium is 

When the rate of evaporation is equal to the rate of condensation, it is called

pK_a values of four acids are given below at 25°C. Indicate the strongest acid.
