Description

Factors Affecting Reaction Rates

Collision theory explains that the rate of a reaction depends on the frequency of collisions and the energy of the colliding particles. Factors such as temperature, concentration, and surface area can influence these aspects.

  1. a

    State one factor that affects the rate of reaction according to collision theory.

    Aim for approximately 1 distinct marking point.
