Rates Of Reactions Flashcards
What is collision theory
The ROR depends in how often and how hard the reacting particles collide with each other. Need a successful collision
What does the ROR depend on
Temperature
Concentration
Surface area
Catalyst
Why does a higher temp increase the chance of a successful collision
As the temp increase the particles move faster, as they move faster they move with more energy and will hit more often, increasing the chance of a successful collision
What effect does a higher concentration have on ROR
If it is more concentrated then there are more particles in a given volume, meaning there will be more collisions and a larger chance of successful collisions
What is the effect of catalysts on ROR
Catalyst speed up the reaction by given the particles a surface to stick to. Increasing the number of successful collisions
