(b) Write equivalent expressions for the rate of the reaction in terms of the appearance or disappearance of the two substances. [Section 14.2]

ANSWER:

Step 1 of 3

As the chemical reaction proceeds, the concentration of reactants decreases, and the concentration of products increases over time.

When an image is provided, the reactants are those chemicals whose concentration decreases along with time, and products concentration increases along with time.
