Rate of Reaction Flashcards
How does concentration affect the rate of reaction?
If the concentration of reactants is increased, there are more reactant particles moving together. There will be more collisions and so the reaction rate is increased.
How does surface area affect the rate of reaction?
If the surface area of a reactant is increased: more particles are exposed to the other reactant. there is a greater chance of particles colliding, which leads to more successful collisions per second. the rate of reaction increases.
How does temperature affect the rate of reaction?
Increasing the temperature increases the average speed of the reactant molecules. As more molecules move faster, the number of molecules moving fast enough to react increases, which results in faster formation of products.
