The phrase that correctly defines chemical equilibrium is a state in which the forward and reverse reactions are proceeding at equal rates

<h3>What is a Chemical equilibrium?</h3>

A Chemical equilibrium refers to the state of a chemical system at which a constant concentration of products and reagents is present.

A Substance turnover occurs only on the particle level which is the reason that chemical equilibrium is also referred to as dynamic equilibrium."

Therefore, the Option B is correct.

Answer:

B. a state in which the forward and reverse reactions are proceeding at equal rates

Explanation:

"Chemical equilibrium is the state of a chemical system at which a constant concentration of products and reagents is present. Reactions, which take place in homogeneous solutions, seem to have come to rest because no changes in concentrations of the participating substances can be determined. Substance turnover occurs only on the particle level, which is why chemical equilibrium is also referred to as dynamic equilibrium."

The osmotic pressure of a solution increases as

s344n2d4d5 [400]

The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.
