When solid nh₄hs and 0.400 mol nh₃(g) were placed in a vessel of volume 2.0 l at 24°c, the equilibrium , for which , was reached. what are the equilibrium concentrations of nh₃ and h₂s?

Equilibrium concentrations of Ammonia and Hhydrogen sulphide are 0.2M respectively

Explanation:

Equilibrium constant is represented by the symbol k, it may be in terms of pressure (Kp) or concentration (Kc). Equilibrium constant is the ratio of the equilibrium concentration of the products of a reaction to the equilibrium concentration of the reactants with each concentration raised to the power of its corresponding coefficients.

There are rules guiding the writing of equilibrium constant, one of them is that the equilibrium constant or concentration for pure liquid or solid is 1

i'm assuming that the correct answer is indeed the first one/ "a"..
