# A question about chemical equilibrium

• samy4408
In summary, chemical equilibrium is a state where the forward and reverse reactions of a chemical reaction occur at the same rate, resulting in no net change in concentration over time. It is established when the forward and reverse reactions have equal rates, and can be affected by temperature. Le Chatelier's principle states that a system at equilibrium will shift in a direction that minimizes the effect of a stress, and this applies to chemical equilibrium as well. The equilibrium constant, K<sub>c</sub> or K<sub>p</sub>, can be calculated by taking the ratio of product to reactant concentrations (or pressures) at equilibrium and measures the extent to which the reaction reaches equilibrium.

Hello we learned about the chemical equilibrium and how to write it's formula in the case of liquid and gaseous phase , what about a reaction involving different phases ? like this one : how do we write the formula for the chemical equilibrium ? do we just ignore the carbon ,is there any rules to write the chemical equilibrium that i forgot ?

Activity of solids is assumed to equal 1.

## 1. What is chemical equilibrium?

Chemical equilibrium is a state in a chemical reaction where the concentrations of reactants and products remain constant over time. This means that the forward and reverse reactions are occurring at the same rate, resulting in no overall change in the amounts of reactants and products.

## 2. How is chemical equilibrium achieved?

Chemical equilibrium is achieved when the rate of the forward reaction is equal to the rate of the reverse reaction. This can be achieved by adjusting the temperature, pressure, or concentrations of reactants and products in the system.

## 3. What factors affect chemical equilibrium?

The factors that affect chemical equilibrium include temperature, pressure, concentrations of reactants and products, and the presence of a catalyst. These factors can shift the equilibrium in either the forward or reverse direction.

## 4. How can the equilibrium constant be calculated?

The equilibrium constant, represented by K, can be calculated by taking the ratio of the concentrations of products to reactants at equilibrium. This value is a constant for a given reaction at a specific temperature and can be used to determine the direction in which the equilibrium will shift.

## 5. Can chemical equilibrium be disturbed?

Yes, chemical equilibrium can be disturbed by changing the temperature, pressure, or concentrations of reactants and products in the system. This will cause the equilibrium to shift in order to maintain a constant ratio between the concentrations of reactants and products.
