A number between 0 and 1, where 1 represents the situation where every collision between two red particles results in the formation of a blue particle. If the RP were set to 0, none of the collisions between red particles would form a blue particle. If the BP were set to 0, none of the collisions of blue particles would form red particles. Allows you to change the number of red particles. Allows you to change the temperature and thus the speed of the particles.
Higher temperatures mean faster speeds and more collisions between particles.
