The equilibrium expression for a reaction is keq=[h+]6[bi2+]2[h2s]3. which of the following could be the reaction? a. 6h+(aq) + bis(s) 2bi2+(aq) + 3h2s(g) b. 2bi2+(aq) + 3h2s(aq) bi2s3(s) + 6h+(aq) c. 6h+(aq) + bi2s3(s) 2bi2+(aq) + 3h2s(g) d. 2bi2+(aq) + 3h2s(aq) bi2s3(aq) + 6h+(aq)

Answer : The correct reaction is, (B)

Explanation :

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

(a) The given balanced chemical reaction is,

So, the equilibrium constant expression will be,

(b) The given balanced chemical reaction is,

So, the equilibrium constant expression will be,

(c) The given balanced chemical reaction is,

So, the equilibrium constant expression will be,

(d) The given balanced chemical reaction is,

So, the equilibrium constant expression will be,

Hence, the correct reaction is, (B)

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

personal, she chose to do it.
