Worked Solution & Example Answer:Chemical reactions are in a state of dynamic equilibrium only when A the reaction involves no enthalpy change B the concentrations of reactants and products are equal C the activation energies of the forward and backward reactions equal D the rate of the forward reaction equals that of the backward reaction. - Scottish Highers Chemistry - Question 17 - 2017
Step 1
D the rate of the forward reaction equals that of the backward reaction.
Answer
In a dynamic equilibrium, the rates of the forward and reverse reactions are equal. This means that the concentration of reactants and products remains constant over time, although both reactions continue to occur. At this point, the system is in a stable state, reflecting the definition of dynamic equilibrium.
