Questions: Which of the following factors would speed up the rate of a chemical reaction? Larger reacting particles Lower temperature Removing the biological catalysts High concentration of reacting particles

Solution Steps

Increasing the concentration of reacting particles generally increases the rate of a chemical reaction. This is because a higher concentration means more particles are available to collide and react.

Larger reacting particles typically slow down the rate of a chemical reaction. This is because larger particles have a smaller surface area relative to their volume, reducing the frequency of effective collisions.

Lowering the temperature usually decreases the rate of a chemical reaction. This is because particles move more slowly at lower temperatures, resulting in fewer collisions and less energy available for the reaction.
