9. rate of reaction Flashcards
1
Q
ways to change rate of reaction
A
changing concentration, temperature, surface area, pressure
2
Q
collision theory
A
the rate of reaction depends on how many successful collisions there are in a given unit of time
3
Q
how do catalysts speed up reactions
A
a catalyst lowers the activation energy of a reaction so the particles need less energy to react and more collisions are successful, making the reaction take place faster
