a chemical engineer is developing a process for producing a new chemical. one step in the process involves allowing a solution of potassium hydroxide to react with a solid. which action would most likely increase the reaction rate for this step? using larger pieces of the solid using a more concentrated potassium hydroxide solution adding water to the system done

Answer

Answer:

B. using a more concentrated potassium hydroxide solution

Explanation:

Step1: Recall reaction - rate factors

Reaction rate depends on concentration, surface - area, etc.

Step2: Analyze each option

  • Using larger pieces of solid: Decreases surface - area, slows reaction.
  • Using more concentrated solution: Increases number of reactant particles, speeds reaction.
  • Adding water: Dilutes solution, decreases reaction rate.
