collision theory & activation energy Flashcards
1
Q
what does the collision theory state?
A
that chemical reactions can only occur when particles collide with each other with enough energy to
2
Q
what is activation energy?
A
the minimum amount of energy that particles must have to react
3
Q
how can you increase the frequency of collisions and rate of reaction?
A
by increasing concentration of reactants in solution, the pressure of reacting gases and surface area of solid reactants
4
Q
what happens as you increase the temperature of a solution?
A
increases frequency of collisions and makes collisions more energetic and so increases the rate of reaction
