  • Which statement correctly describes a reaction in dynamic equilibrium?
    In dynamic equilibrium, the rate of the forward reaction equals the rate of the reverse reaction, and the concentrations of reactants and products remain constant over time.
  • What set of conditions is required for Hardy-Weinberg equilibrium?
    Large population size, random mating, no mutation, no migration, no natural selection
  • What is true about the equilibrium of chemical reactions?
    At equilibrium, the rates of the forward and reverse reactions are equal.
  • How is chemical equilibrium correctly described?
    The forward and reverse reactions occur at the same rate.
  • What best describes what occurs at chemical equilibrium?
    The rates of the forward and reverse reactions are equal.
  • Which statement describes a reaction at equilibrium?
    A reaction at equilibrium has the forward and reverse reactions occurring at the same rate, resulting in constant concentrations of reactants and products.
  • What best describes a system at chemical equilibrium?
    The rates of the forward and reverse reactions are equal.
  • What describes a reaction that is at equilibrium?
    The rates of the forward and reverse reactions are equal.
  • At what point in the process of diffusion is dynamic equilibrium reached?
    Dynamic equilibrium in diffusion is reached when the concentration of particles is uniform throughout the system, and the rate of movement in all directions is equal.
  • Are most chemical reactions at equilibrium in living cells?
    No, most chemical reactions in living cells are not at equilibrium; they are often driven by energy inputs to maintain life processes.
  • Which statement describes this reaction at equilibrium?
    At equilibrium, the forward and reverse reactions occur at the same rate, and the concentrations of reactants and products remain constant.
  • What is always true about a reversible chemical reaction?
    A reversible chemical reaction can proceed in both the forward and reverse directions, and at equilibrium, the rates of these reactions are equal.
  • What best describes chemical equilibrium?
    The rates of the forward and reverse reactions are equal.
  • Are most chemical reactions in living cells at equilibrium?
    No, most chemical reactions in living cells are not at equilibrium; they are often driven by energy inputs to maintain life processes.
