Interpretation: Between steel beam and powdered iron, the one which dissolved faster is to be determined and also the difference in rate of the reaction of both cases needs to be explained.
Concept introduction: For a reaction to occur, the collision of reactant particles in correct orientation with sufficient energy is required. Rate of a reaction is the speed at which a reaction occurred.

Answer to Problem 7E
Powdered iron has faster
Explanation of Solution
Surface area is one of the factors that affect the rate of
There are many factors that affect the rate of a chemical reaction, such as, temperature, concentration, surface area etc.
