Essential Chemistry for IGCSE - Rate Of Reaction (Section 1 - No. 23)
Which of the following statements is true about the effect of temperature on reaction rate?
Increasing temperature increases the number of collisions between particles, thus increasing the reaction rate.
Increasing temperature decreases the kinetic energy of reactants, thus decreasing reaction rate.
Increasing temperature provides the particles with more energy, thus increasing the reaction rate.
Increasing temperature increases the activation energy, thus increasing the reaction rate.
Explanation
Increasing the temperature increases the kinetic energy of the reactant molecules, so the particles have more energy to react.
