Which of the following statements describes how a clock reaction can be used to infer reaction orders?

• A. The rate is determined solely from the final products after the rapid change.
• B. The rate is inferred from the length of the induction time, but not dependent on initial conditions.
• C. The rate is inferred from the induction time, and varying initial concentrations reveals the orders.
• D. The rate can only be measured by stopped-flow instruments.

Answer: (C)
