A student made a graph to show the chemical equilibrium position of a reaction. The student forgot to label the y-axis of the graph.

A graph is shown with two graph lines. One graph line starts at a higher position on the y axis and slopes downwards towards the right. The other graph line starts at a lower position on the y axis and slopes upwards towards the right. The two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. A vertical line is shown at a point where the two graph lines finally became parallel to the x axis. This vertical line is labeled equilibrium. The title on the x axis is Time and an arrow pointing towards the right is shown above Time. The title on the y axis is left blank.

What best explains the label that the student should use on the y-axis?

Concentration, because as the amount of product decreases, the amount of reactant increases over time.
Reaction rate, as the rates of forward and backward reactions become equal at equilibrium.
Concentration, because the amounts of reactants and products remain constant after equilibrium is reached.
Reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.

The y axis is concentration since  the amounts of reactants and products remain constant after equilibrium is reached.

What is equilibrium?

In a chemical reaction system, equilibrium is said to be attained when the rate of forward reaction and the rate of reverse reaction are equal. This is indicated by the straight line.

Therefore, the correct label for the y axis is concentration, because the amounts of reactants and products remain constant after equilibrium is reached.
