For the equilibrium 2H2S(g) ⇋ 2H2(g) + S2(g) Kc = 9 .0X 10-8 at 700°C
the initial concentrations of the three gases are 0.300 M H2S, 0.300 M H2, and 0. 1 50 M S2' Determine the equilibrium concentrations of the gases.

Equilibrium concentrations of the gases are

Explanation:

We are given that  for the equilibrium

Temperature,

Initial concentration of

We have to find the equilibrium concentration of gases.

After certain time

2x number of moles  of reactant reduced and form product

Concentration of

At equilibrium

Equilibrium constant

Substitute the values

By solving we get

Now, equilibrium concentration  of gases
