What effect does an increase in temperature have on the collision of reactant particles?

Back

Increase collision between the particles thus increasing the rate.

How does increasing the concentration affect the speed of reaction?

Back

increasing collisions

Front

Factors that increase the rate of a reaction.

Back

Increasing temperature, increasing concentration, increasing surface area.
