rate of reaction
In a nutshell
- Chemical reactions happen at different rates. Reactions that occur slowly have a low rate of reaction.
- The collision theory states that for a chemical reaction to occur, the reactant particles must collide with the right amount of energy and orientation.
- The rate of reaction depends on the proportion of effective collisions between reactants. The more effective collisions there are, the faster the rate of reaction.
- The rate of a chemical reaction is affected by a number of factors such as temperature of the reaction, concentration of the reactants, surface area of one reactant or using a catalyst.
