Which of the following statements is true about chemical equilibrium? Select all that apply. At chemical equilibrium, the reactants have been completely consumed. At chemical equilibrium, both reactions stop completely. At chemical equilibrium, the concentrations of the species involved in the reaction stay constant (in the absence of an external perturbation). At chemical equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
