Here's a taster:

Factors Affecting Rate of Reaction
· Temperature
· Use of a catalyst
· Concentration
· Surface area
· Pressure (if it's a gas)
· Not enough energy so existing bonds cannot be broken
· The particles are moving in the wrong orientation and therefore
more collisions are unsuccessful…read more

Here's a taster:

How to Speed Up the Rate of Reaction
· Increase the collision frequency Each of these
points can be done
· Increase the energy of particles in several ways
· Alter the reaction pathway so less energy is required…read more

Here's a taster:

Rate of Reaction Definition
· The rate at which reactants are being converted into products
· E.g. the change in concentration per unit time
· Usual units: mol dm-3 s-1…read more

Here's a taster:

Collision Theory Definition
· Particles must collide to react. Not all collisions result in a reaction.
The particles must have a minimum amount of energy (activation
energy) between them for a reaction to occur
· They must also collide in the correct orientation…read more
