Temperature, Concentration, Catalyst, Surface area 1 of 9 When the temperature is increased, the particles... ... more faster. 2 of 9 When moving faster, there's a higher chance of them... ... colliding more frequently. 3 of 9 The faster they move... ... the more energy they have. 4 of 9 If a solution has a higher concentration, it means that... ... there are more particles of reactant, making the collision more likely. 5 of 9 You can increase the surface area by... ... crushing the solid into a powder form. 6 of 9 Having a bigger surface area allow for... ... more collisions to take place as there's more area to work with. 7 of 9 A catalyst is... ... a substance which increases the speed of a reaction without being used up in the reaction. 8 of 9 A catalyst increases the rate of reaction because... ... it provides a surface for the reacting particles to stick to so they can bump into each other successfully. 9 of 9
