Consider the following equilibrium: 4ko2(s) + 2h2o(g) 4koh(s) + 3o2(g) which of the following is a correct equilibrium expression? keq=[koh]4[o2]3[ko2]4[h2o]2 keq=[h2o]2[o2]3 keq=[ko2]4[h2o]2[koh]4[o2]3 keq=[o2]3[h2o]2

Explanation:

The equilibrium constant (Keq) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. In Keq we include gases and aqueous species, but not solids nor pure liquids because their concentration remains almost constant over time.

Let's consider the following reaction.

4 KO₂(s) + 2 H₂O(g) ⇄ 4 KOH(s) + 3 O₂(g)

Then, the equilibrium constant is:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
