Rates Of Reactions

Question 0

What is collision theory

Answer 0

The ROR depends in how often and how hard the reacting particles collide with each other. Need a successful collision

Question 1

What does the ROR depend on

Answer 1

Temperature
Concentration
Surface area
Catalyst

Question 2

Why does a higher temp increase the chance of a successful collision

Answer 2

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

Question 3

What effect does a higher concentration have on ROR

Answer 3

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

Question 4

What is the effect of catalysts on ROR

Answer 4

Catalyst speed up the reaction by given the particles a surface to stick to. Increasing the number of successful collisions
