When the reactants are heated, the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy. If more molecules hit each other with enough energy to react, then the rate of the reaction increases.
Best Answer: As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10Â°C rise in temperature.The more finely divided the solid is, the faster the reaction happens. catalyst is to help to increase the rate of chemical reaction by changing the energy pathway to a lower activation energy pathway. That is increasing the frequency of collisions between reactants. The higher the collision per unit the higher the rate of reaction.
