Question

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

Answer 1

using a more concentrated potassium hydroxide solution
Concentration is one of the factors that affect the rate of reaction

The higher the concentration, the higher the reaction rate

Answer 2

the 2nd one is correct

The option that would most likely increase the rate for a more contentrated potassium hydrogene

:) hope this helps
