Select the correct collision theory explanation for changing the rate of the given chemical reaction.

refrigerate food to keep it from spoiling.

add inert water to a reaction solution.

compress the air/fuel mixture inside an engine cylinder with a piston.

raise the boiling point of water with a pressure cooker.

grind a metal into a fine powder.

Explanation:

According to collision theory, more is the number of collisions between solute and solvent particles more will be the rate of reaction.

Refrigerate food to keep it from spoiling - Here particles will collide with less force as decrease in temperature will cause an increase in potential energy of particles.Add inert water to a reaction solution - Here also particles will collide less frequently.Compress the air/fuel mixture inside an engine cylinder with a piston - Here particles will collide more frequently as increasing the pressure will bring the molecules close to each other and thus there will be more number of collisions.Raise the boiling point of water with a pressure cooker - Increase in temperature will also cause increase in number of collisions.Grind a metal into a fine powder - More surface area will also provide more number of collisions.

Hi. where is the graph?
