Significate of equilibrium constant

The video tutorial explains the concept of the equilibrium constant KC and its impact on chemical reactions. It describes how different KC values influence the direction of equilibrium, favoring either product or reactant formation. The tutorial provides examples, such as the Haber process for ammonia production and the formation of nitric oxide, to illustrate these concepts. It concludes with a summary of the relationship between KC and the extent of reaction.

What does a KC value greater than 10^3 indicate about a chemical reaction?

• The reaction does not proceed in any direction.

• The reaction is at equilibrium with equal amounts of reactants and products.

• The reaction favors the formation of products.

• The reaction favors the formation of reactants.

Which of the following is true for a reaction with a KC value between 10^-3 and 10^3?

• The reaction favors the formation of reactants.

• The reaction does not proceed in any direction.

• The reaction contains significant amounts of both reactants and products.

• The reaction favors the formation of products.

In the Haber process, what does a KC value of 3.7 x 10^8 suggest?

• The reaction favors the formation of products.

• The reaction does not proceed in any direction.

• The reaction favors the formation of reactants.

• The reaction is at equilibrium with equal amounts of reactants and products.

What can be concluded about a reaction with a KC value less than 1?

• The reaction favors the formation of reactants.

• The reaction is at equilibrium with equal amounts of reactants and products.

• The reaction favors the formation of products.

• The reaction does not proceed in any direction.

What does the KC value indicate about the extent of a chemical reaction?

• It determines the speed of the reaction.

• It measures the pressure of the reaction system.

• It indicates the temperature at which the reaction occurs.

• It shows the direction and extent to which a reaction proceeds.
