| A | B |
|---|
| reactions occur | 2 substances must come into contact & there needs to be enough energy |
| activation energy | amount of energy needed to cause a reaction |
| catalysts | substances that increase the rate of reactions by lowering activation energy |
| catalysts only affect | the rate of reaction |
| exothermic | reaction that releases energy |
| endothermic | reaction that absorbs energy |
| equilibrium | the rate of the forward reaction is = to the rate of reverse reaction |
| increasing the surface area of a substance | boosts reaction rate |
