Temperature, concentration, pressure and the use of catalysts affect reaction rate. Part of Chemistry (Single Science) Rates of reaction and energy changes Save to My Bitesize Save to My Bitesize ...

Students saw that the rate of the reaction can be sped up if the reactants are warmed and slowed down if the reactants are cooled. Explain that there are many reactions that will not occur at all at ...

(The temperature of a solution is a measure of its molecules’ average motion and energy.) Can you guess whether fast-moving molecules or slow-moving ones will speed the reaction time?

Rates of reaction - Edexcel Core practical - measuring the production of a gas The greater the frequency of successful collisions between reactant particles, the greater the reaction rate.
