Which of the following would result in an increase in the chemical reaction?
A. Adding more of the product
B. Decreasing the concentration of the reactant
C. Sealing the reaction in an airtight container
D. Using a mortar and pestle to grind a solid reactant to a powder
Crushing a solid reactant into powder increases the surface area of the reactant, thereby increasing chemical reaction. This is because more of the reacting molecules or ions are exposed to the other reactant, which increases the chance of particles colliding and leads to more successful collisions per second.
Therefore, the Correct Answer is D.
