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 the reaction rates of the forward and backward reactions are always zero.
- A state where the reaction rates of the forward and backward reactions are never equal.
- A state where the concentration of products is always higher than the concentration of reactants.
When does chemical equilibrium occur?
When does chemical equilibrium occur?
- When the forward reaction stops completely.
- When the reverse reaction stops completely.
- When the forward reaction proceeds at the same rate as the reverse reaction. (correct)
- When the forward reaction proceeds at a faster rate than the reverse reaction.
What does it mean if the equilibrium position is 'far to the right'?
What does it mean if the equilibrium position is 'far to the right'?
- The reaction has stopped completely at equilibrium.
- Nearly all the reactants are consumed at equilibrium. (correct)
- Hardly any product is formed from the reactants at equilibrium.
- The concentration of products is always higher than the concentration of reactants at equilibrium.
