a reaction between particles will only take place if:
particles collide
they collide with sufficient energy
they collide with the correct orientation
increase the energy of each particle
by increasing temperature
more kinetic energy, particles move faster, collide more frequently
increases the average energy of the particles
maxwell-boltzmann distribution- more particles reacting after activation energy, average particle more energy, however area under curve doesnt increase as havent increase number of molecules
decrease amount of energy required
add a catalyst
provides an alternative route for the reaction with a lower activation energy
