This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)

could you say something about the particle collision theory on this please?
Increase in concentration = +Increase in rate of reaction+more particles in a given volume +Particles collide more often+therefore more successful collisions per second.Increase in temperature= +Increase in rate of reaction +Particles have more energy+therefore more collisions have the required activation energy+which results in more successful collisions per secondIncrease in surface area=+Increase in rate of reaction+More particles in contact with the other reactant+Particles collide more often+which results in more successful collisions per secondA CATALYST provides an alternative pathway for the reaction to start, which requires a low activation energy.(Activation energy is the amount of energy required for a reaction to occur)Happy revising people!!
