Answer

Answer:

D. Reduce the volume of the container.

Explanation:

Step1: Understand reaction - rate factors

Increasing temperature, surface - area, pressure or concentration speeds up reactions.

Step2: Analyze each option

  • Lowering temperature slows down molecular motion, reducing collision frequency.
  • Using larger pieces of calcium hydroxide decreases surface - area, reducing reaction rate.
  • Lowering pressure decreases the number of gas molecules per unit volume, reducing collision frequency.
  • Reducing the volume of the container increases the pressure of the gas ($CO_2$), increasing the collision frequency between $Ca(OH)_2$ and $CO_2$ molecules, thus speeding up the reaction.
