Explain, in terms of particles, concentration, and reaction rate, what you expect to happen when methane gas (CH4) and hydrogen sulfide gas (H2S) are sealed in a flask and reach a state of equilibrium.

Question

CH4 (g) +2 H2S (g) --><--- CS2 (g) + 4 H2 (g)

Answer 1

reaction rates each way are equal, by definition of equilibrium.

pressure will be greater at equilibrium, as (balanced equation) there were 3 moles on left, 5 moles on right, so to whatever degree it goes to the right, it makes more particles, and increases pressure.
