Products have less energy than reactants
Products have more energy than reactants
Energy is given out to the surroundings
Energy is taken in from the surroundings
Particles must collide
Must collide with at least the activation energy
Must collide at the correct angle
Speed up reactions without being used up themselves
Provide a different pathway with lower activation energy
No, the overall energy change stays the same
Yes, all reactions need activation energy
