To make an experiment a fair test you must
Reactions can happen if the colliding particles have enough energy
At higher temperatures particles move faster and collide more often
only change one variable at a time while keeping all other conditions the same
Speeds up the rate of a reaction without being used up
Use smaller marble chips
There are more particles so there are more collisions
Both reactions occurred at the same speed.
Increasing the size of reactant particles
Which of the following statements about collisions is correct?
