. Explain what it means that a reaction has reached a state of chemical equilibrium. Explain why equilibrium is a dynamic state: Does a reaction really “stop” when the system reaches a state of equilibrium? Explain why, once a chemical system has reached equilibrium, the concentrations of all reactants remain constant with time. Why does this constancy of concentration not contradict our picture of equilibrium as being dynamic? What happens to the rates of the forward and reverse reactions as a system proceeds to equilibrium from a starting point where only reactants are present?

Interpretation Introduction

Interpretation:

The explanation of the meaning of given statement “has reached a state of chemical equilibrium” is to be stated. The reason behind the explanation of equilibrium is a dynamic state is to be described. The validation of the fact that a reaction really “stop” when the system reaches a state of equilibrium is to be stated. The explanation of the given statement that as once a chemical system has reached equilibrium, the concentrations of all reactants remain constant with time is to be stated. The reason for the statement that is the constancy of concentration not contradicts the picture of equilibrium as being dynamic is to be stated. The explanation regarding the progress of the reaction in which a system proceeds to equilibrium from a starting point where only reactants are present is to be stated.

Concept Introduction:

There are two types of reactions, reversible and irreversible reactions. In reversible reactions, the products are again converted into the starting materials. In the irreversible reactions, products do not convert into the starting materials or reactants of the reaction. The different types of arrows are used to represent reversible and irreversible reactions.

Explanation

A state of chemical equilibrium describes that the rates of forward and backward reactions are same at this point. The equilibrium is a dynamic state becausein this state, the changes occur at the microscopic level. It implies that a reaction does not “stop” when the system reaches a state of equilibrium. However, during the chemical equilibrium of a reaction, the reaction occurs simultaneously in both th...
