Here are the choices:

Warm air rises while cold air falls.

The warmer air contains less water vapor per unit of volume.

The warmer air contains more water vapor per unit of volume.

Moist air has lower density than dry air does.

The best answer is: <em>The warmer air contains more water vapor per unit of volume. </em>

In a reversible chemical reaction at equilibrium, the concentration of X (the reactant) is 0.75 mol/L, and the concentration of

frosja888 [35]

Answer : The value of $K_{eq}$ is, 3

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

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 and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$X\rightleftharpoons Y$

The expression of $K_{eq}$ will be,

$K_{eq}=\frac{[Y]}{[X]}$

Given:

[X] = 0.75 mol/L

[Y] = 2.25 mol/L

Now put all the given values in the above expression, we get:

$K_{eq}=\frac{2.25}{0.75}$

$K_{eq}=3$

Therefore, the value of $K_{eq}$ is, 3
