Questions and Answers
What is chemical equilibrium?
What is chemical equilibrium?
- A state in which both the reactants and products are present in concentrations which have no further tendency to change with time (correct)
- A state where reactants and products are absent
- A state where reactants are completely consumed and products are formed
- A state where only reactants are present
What happens when a reaction is at chemical equilibrium?
What happens when a reaction is at chemical equilibrium?
- The forward reaction stops
- The reverse reaction proceeds faster than the forward reaction
- The forward reaction proceeds at the same rate as the reverse reaction (correct)
- The forward reaction proceeds faster than the reverse reaction
When do we say the equilibrium position is 'far to the right'?
When do we say the equilibrium position is 'far to the right'?

Study Notes
Chemical Equilibrium
- Chemical equilibrium is a state in a chemical reaction where the rates of forward and reverse reactions are equal, resulting in no net change in the concentrations of reactants and products.
Characteristics of Chemical Equilibrium
- At chemical equilibrium, the reaction is not "stopped" or "completed", but rather, the forward reaction and reverse reaction occur at the same rate, resulting in a dynamic equilibrium.
- The concentrations of reactants and products remain constant at equilibrium, but the reaction is still active.
Equilibrium Position
- The equilibrium position is said to be 'far to the right' when the reaction is largely complete, meaning the majority of reactants have been converted to products.
History of Chemical Equilibrium
- The concept of chemical equilibrium was developed in the late 19th century, providing a fundamental understanding of chemical reactions.
Equilibrium Concentration Positions
- The equilibrium concentration position of a reaction refers to the ratio of the concentrations of products to reactants at equilibrium, which can vary depending on factors such as temperature, pressure, and catalysts.
