Anything that increases the contact between the reactinp particles will increase the rate ofthe reaction This can be done in several ways: 1.By increasing the concentration of the reactants that there are more particles present. The particles will collide into one another more often and will therefore react to form products more rapidly By increasing the pressure inside the reaction vessel so that the particles become squashed together and ...
