Question 12

THE RATES OF REACTION DEPENDS ON

Answer 12

1) THE COLLISION FREQUENCY OF REACTING PARTICLES (HOW OFTER THEY COLLIDE)- THE MORE COLLISIONS THERE ARE THE FASTEE THE REACTION IS

2) THE ENERGY TRANSAFERRED DURING A COLLISION- PARTICLES HAVE TO COLLIDE WITH ENOUGH ENERGY FOR THE COLISSION TO BE SUCCESFUL
