Interpretation:
A system at equilibrium appears to be unchanging on the macroscopic level, is it also unchanging at the molecular level, needs to be explained.
Concept introduction:
That state at which the rate of forwarding reaction becomes equal to the rate of the reverse reaction is said to be equilibrium.

Answer to Problem 7RQ
No, the forward and reverse reaction in a
Explanation of Solution
On the basis of the macroscopic level, the forward and reverse reactions are still occurring but with the same reaction rate. But on the basis of the molecular level, the concentration of products and reactants does not change or it will remain the same.
On the macroscopic level, at equilibrium appears to be unchanging but at the molecular level it becomes to change.
