Rates of Reaction Flashcards
(4 cards)
1
Q
what is the rate of a chemical reaction?
A
how fast the reactants are changed into products
2
Q
what is activation energy?
A
the amount of energy the particles need to react - particles that collide with less energy than this will just rebound and remain unchanged
3
Q
what does the rate of a reaction depend on?
A
- the collision frequency of reacting particles - the more collisions the faster the reaction is
- the energy transferred during a collision - particles have to collide with enough energy for the collision to be successful
4
Q
the greater the activation energy…
A
the more energy needed to start the reaction
