Rate of Reaction CGP Topic 7
The three necessary things for a collision to occur:
1. Reactants have to collide
2. Have to collide in the correct orientation
3. Have to collide with enough energy
What affects the rate of reaction?
Temperature

Maxwell-Boltzmann Distribution
A Maxwell-Boltzmann Distribution is a probability distribution used
for describing the speeds of various particles within a stationary
container at a specific temperature; in short, it shows the number of
molecules per unit speed. The distribution is often represented with
a graph, with the y-axis defined as the number of molecules and the
x-axis defined as the speed
