AQA A Level Chemistry复习笔记1.7.4 Effect of Temperature on Reaction Rate

Temperature & Rate of Reaction


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 successful6.1.6-Effect-of-temperature


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
