Temperature & Rate of Reaction

• Increasing the temperature of the reaction mixture increases the?rate of reaction?in the following two ways:
  • At higher temperatures, the particles are moving faster, so collide more frequently. A higher number of collisions in total mean a higher?number?of successful collisions
  • At higher temperatures, a higher proportion of the molecules have the activation energy or more. This means that a higher?proportion?of collisions are?successful

   

An increase in temperature causes an increase in the kinetic energy of the particles. The number of collisions increases and the proportion of successful collisions increases
