At equilibrium no chemical reaction takes place?

Answer 1

No. For a reaction A -> B , no reactants means the reaction goes to completion. For many types of reactions, the arrow goes in both directions (right and left), in other words B -> A also! The equilibrium point is somewhere in between at a concentration where the reaction progresses to make B at the same rate that B converts back to A. Le Chatelier's principle shows that by removing some of B, the eqilibrium will need to re-establish itself, hence the reaction proceeds to the right to make more products (more B). This is how you force a reaction to make more products when it is limited by an equilibrium.

Answer 2

At equilibrium, the rates of the forward and reverse reactions are equal, so there is still a chemical reaction occurring but the concentrations of reactants and products remain constant.

Answer 3

False
