35. slow it down (lower temperature slows down the kinetic energy of particles, reducing the frequency and force of collisions between reactant molecules)
36. speed it up (more reactant molecules present means a greater likelihood of collisions between molecules, increasing the reaction rate)
37. speed it up (smaller reactant pieces increase the surface area for collisions between molecules, increasing the reaction rate)
How would each of these factors influence the rate of a reaction?
A. speed it up B. slow it down C. would have no effect
35. reduce temperature
36. increase the concentration of reactant
37. crush reactant into smaller pieces
