C2 - Collision Theory Rate of reaction Catalysts Factors 0.0 / 5 ? ChemistryRate of reactionGCSEAQA Created by: Connie JoyceCreated on: 25-08-14 12:06 How do more collisions affect the rate of reaction? It increases it. Partices have to collide hard enough with enough energy to react. 1 of 6 How does a higher temperature affect the rate of reaction? It increases the collisions. The particles move quicker so they'll collide more often. 2 of 6 How does a higher cencentration affect the rate of reaction? It increases the collisions. There are more particles so collisions are more likely. 3 of 6 How does a larger surface area affect the rate of reaction? It increases the collisions. There is more area to work on so the particles have a greater chance to collide with. 4 of 6 What is a catalyst? A catalyst is a substance which speeds up a reaction, without being changed or used up in the reaction. 5 of 6 How do catalysts reduce costs in industrial reactions? The plant doesn't have to run as long. 6 of 6
