Final answer:
Because of process loss, actual output rarely equals potential output in chemical reactions.
Step-by-step explanation:
The statement is true. Because of process loss, actual output rarely equals potential output in chemical reactions. Process loss refers to the factors that can decrease the amount of product obtained in a reaction, such as incomplete reactions, formation of unwanted products, and inefficiencies in separation procedures. The amount of product actually obtained is called the actual yield, which is always less than or equal to the theoretical yield.
