Why does increasing the temperature of a chemical reaction speed up the reaction?
Increasing the temperature will increase how fast the particles will move; the faster the particles move, the less they bump into each other, speeding up the reaction.
Increasing the temperature of the substance will slow down the movement of the particles, therefore allowing the reaction to speed up.
Increasing the temperature of the substance does not speed up the reaction.
When the temperature of the substance is increased, the particles within it will move faster. The particles will move faster and will bump into each other more, increasing the speed of the chemical reaction.
