Question

What best explains the label that the student should use on the y-axis? reaction rate, as the rate of forward and backward reactions become equal at equilibrium. concentration, as the concentration of reactants and products become equal at equilibrium. reaction rate, as the rate of forward reaction increases and the rate of backward reaction decreases with time. concentration, as the concentration of products decreases and that of reactants increases over time.

Answer 1

The answer is:

Concentrations, because the amounts of reactants and products remain constant after equilibrium is reached.
