What is equilibrium?
In a chemical equilibrium, the forward and reverse reactions occur:
Chemical equilibrium is called dynamic because:
At equilibrium, the concentration of reactants and products:
A reaction can reach chemical equilibrium only in:
Which of the following can disturb a chemical equilibrium?
According to Le Chatelier's principle, when a stress is applied to a system at equilibrium, the system:
Adding more reactant to a system at equilibrium generally shifts the equilibrium:
Removing a product from a system at equilibrium generally shifts the equilibrium:
A catalyst affects a system at equilibrium by:
Does a catalyst change the position of equilibrium?
Increasing pressure in a gaseous equilibrium favors the side with:
Decreasing pressure in a gaseous equilibrium favors the side with:
For an exothermic reaction, heat can be considered as:
For an endothermic reaction, heat can be considered as:
Which factor does NOT usually affect the position of chemical equilibrium?
The equilibrium constant (K) depends mainly on:
Which condition is necessary for dynamic equilibrium to be established?
At dynamic equilibrium, the concentrations of reactants and products are:
What happens when the concentration of a product is increased?
