JON CHASE:'Chemical reactions are all about collisions between particles, 'and a rate of reaction depends on how frequently particles collide 'and with how much energy. JON CHASE:'There four methods ...

The greater the frequency of successful collisions between reactant particles, the greater the reaction rate. Temperature, concentration, pressure and the use of catalysts affect reaction rate. Heat ...
