An example of this is temperature. Increasing the temperature in a reaction will cause there to be increased kinetic energy within particles so they will move around faster which will increase the rate of reaction because the particles will be colliding more at the right orientation and with enough energy. And if you decrease the temperature in a reaction it will cause the particles to have less kinetic energy so they will move around slower so the collisions within the particles will have less energy as they are moving with less energy.

This is done by creating an alternate pathway for the particles to collide with each other ultimately increasing the chance they will collide at the correct orientation. Since this activation energy has been lowered less energy is required for the particles to collide at the correct orientation resulting in more successful collisions than without the presence of a catalyst.
