Question

Provide the expressions for the equilibrium constant Keq:
CH4(g) + 2H2SE(g) ⇄ 4H2(g) +CSe2(g)

Answer 1

Keq = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².

Step-by-step explanation:

• The equilibrium constant expression is the ratio of the concentrations of the products over the reactants.

• For the reaction:

CH₄(g) + 2H₂Se(g) ⇄ 4H₂(g) + CSe₂(g).

∴ Keq = [products]/[reactants] = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².
