What is keq for the reaction n2 + 3h2 2nh3 if the equilibrium concentrations are [nh3] = 3 m, [n2] = 1 m, and [h2] = 2 m?

a. keq = 0.75

b. keq = 1.5

c. keq = 4.5

d. keq = 1.125

The Keq for the reaction of the ammonia formation has been the 1.125 mol/L. Thus, option D is correct.

Keq has been the equilibrium constant for the chemical reaction. The Keq can be calculated from the balanced chemical equation and has been the ratio of the concentration of the product to the reactants with respect to the stoichiometric constants.

The balanced chemical equation for the reaction has been:

The equilibrium constant can be given as:

Equilibrium constant =

The given concentrations of the compounds have been:

Ammonia = 3 M, Nitrogen = 1 M, and Hydrogen = 2 M.

Substituting the values:

Equilibrium constant =

Equilibrium constant =

Equilibrium constant = 1.125 mol/L.

The Keq for the reaction of the ammonia formation has been the 1.125 mol/L. Thus, option D is correct.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
