What is the equation to calculate the rate of a reaction?
rate = 1/ time
What is collision theory?
For a reaction to occur, particles most collide together with enough energy to react.
Successful collisions are ones that result in a reaction
Reaction rates are increased when the energy of the collisions is increased and when the frequency of collisions is increased
What is activation energy?
The minimum energy needed for a reaction to occur
What is the effect of concentration on collision theory?
There are more particles in the same volume
There are more successful collisions between particles in a given time
The rate of reaction is faster
What is the effect of surface area on collision theory?
There are more particles on the surface exposed
There are more successful collisions between particles in a given time
The rate of reaction is faster
What is the effect of temperature on collision theory?
Particles are moving faster, so there are more frequent collisions
Particles have more energy so more of the particles have activation energy and react when they collide
Therefore there are more successful collisions between particles in a given time
