Indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium after reactant or product is added. C_4H_4(g) + Cl_2(g) C_2H_4Cl_2(g) after increasing the concentration of CI_2 after increasing the concentration of C_2H_4CI_2
The Correct Answer and Explanation is :
In the given chemical equilibrium:
[
C_4H_4(g) + Cl_2(g) \rightleftharpoons C_2H_4Cl_2(g)
]
we can analyze the changes when the concentrations of reactants or products are altered.
1. Increasing the concentration of Cl_2 (chlorine gas):
According to Le Chatelier’s Principle, if the concentration of one of the reactants (Cl_2) is increased, the equilibrium will shift to the right to counterbalance the change. The system will try to consume some of the excess chlorine gas by producing more of the product, C_2H_4Cl_2 (1,2-dichloroethane). Consequently, this will lead to an increase in the concentration of C_2H_4Cl_2 and a slight decrease in the concentration of C_4H_4 (butadiene) as it is consumed in the reaction.
Thus:
- The concentration of Cl_2 decreases as it is used up in the reaction.
- The concentration of C_4H_4 decreases as it reacts to form more C_2H_4Cl_2.
- The concentration of C_2H_4Cl_2 increases as it is produced.
2. Increasing the concentration of C_2H_4Cl_2 (1,2-dichloroethane):
When the concentration of the product, C_2H_4Cl_2, is increased, the system will attempt to counter this change by shifting the equilibrium to the left, towards the reactants. This is because the system wants to decrease the excess product to restore equilibrium. As a result:
- The concentration of C_2H_4Cl_2 will decrease as some of it will decompose into the reactants.
- The concentration of Cl_2 and C_4H_4 will increase as they are produced in the reverse reaction.
Summary:
- Increasing the concentration of Cl_2 results in more C_2H_4Cl_2 and less C_4H_4.
- Increasing the concentration of C_2H_4Cl_2 leads to more Cl_2 and C_4H_4.
Now, I’ll generate an image that visually represents the equilibrium reaction.
Here is the image illustrating the equilibrium reaction for the given chemical equation. The diagram shows how the system will shift based on changes in the concentrations of reactants or products, following Le Chatelier’s Principle. Let me know if you need further explanation or adjustments!
