Which of the following accurately describes the variation of reaction rates for a reversible reactio — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Initially, only reactants are present, so the forward rate ($r_f$) is maximum and backward rate ($r_b$) is zero. As products form, $r_b$ increases and $r_f$ decreases due to consumption of reactants. At equilibrium, both rates become equal ($r_f = r_b$) and constant, and neither is zero (dynamic equilibrium).
