Rates of reaction
Frequency of collisions increases due:
- Adding a small change in temperature in order to have a large effect on the rate of reaction (and energy of the particles)
- Reactions in solutions go faster at higher concentration because .... (see title)
- Increasing the pressure increases the rate of a reaction of two gases because ... (see title). (and there are more molecules in the same volume).
Rate of reaction = amount of reactant used OR amount of product formed
Activation energy = Minimum amount of energy that particles must have in order to react.
Factors that increase rate of a reaction: Temperature. Surface area of solids. Using a cataylst (because a cataylst speeds up reactions).
