Rate of Reactions and collision theory

Equation of rate of reaction?

amount of reactant/time = amount of product formed/time

What effects the rate of reaction?

temperature, surface area, Catalyst, Concentration, pressure

What happens if there are more collisions?

There are more successful collisions

How does temperature increase the rate of reaction?

It increases the Energy, Witch makes the particles more faster and collide more frequently giving more successful collisions

How does Concentration(solutions) increase the rate of reaction?

By adding more particles per unit of volume making collisions more frequent

How does Pressure(gas) increase the rate of reaction?

By Increasing the amount of particles per unit of volume

How does surface area increase the rate of reaction?

More particles are exposed which allows other particles to collide increasing the rate of reaction

Do catalysts get used up during rate of reaction?

No, we don’t include them in the reaction equation

How does catalysts increase the rate of reaction?

By offering an alternative reaction pathway
