A student adds iron filings to a copper(II) chloride solution at room temperature. A balanced equation for the reaction that occurs is shown below. Fe_(s) + CuCL₂(aq) → FeCL₂(aq) + Cu_(s)
Which of the following changes would most likely increase the reaction rate?

Question

Quizplus · Accepted Answer

Increasing the concentration of the CuCl2 solution increases the number of Cu2+ ions in the solution, which can interact with the iron filings, thus increasing the reaction rate.
