A chemical system at equilibrium is referred to as dynamic because the:
A) rates of the forward and reverse reactions continue changing
B) forward and reverse reactions continue reacting
C) value of the equilibrium constant (K) changes
D) concentrations of the components continue changing
Answer (3)
B is the correct answer because while the concentrations stay the same (as does the rate constant), the reaction still continues, the forward and reverse reactions continue, but occur at the same rate.
A chemical system at equilibrium is dynamic because the forward and reverse reactions continue reacting at equal rates, giving the illusion of unchanging conditions. ;
The correct answer is B) forward and reverse reactions continue reacting. This reflects that in a dynamic equilibrium, both reactions are ongoing but occur at equal rates, leading to constant concentrations of reactants and products.
