Concentration

Subdecks (1)

How does increasing concentration or pressure increase the rate of reaction? 
Higher concentration means more particles are crowded closer together
Since particles are crowded closer together, they collide more often and so there’s more successfully collisions
Increasing the pressure of reacting gases also increases the frequency of collisions
Analysis of rate of reaction concentration investigation:
-increasing the concentration increases the rate of reaction
What is the difference of using a 2mol/dm³ compared to using a 1mol/dm³ acid in the rate of reaction concentration investigation? 
The 2mol/dm³ reacted quicker than the 1mol/dm³
What type of concentration is this?
High concentration
What type of concentration is this? 
Low concentration
Use collision theory to explain why increasing the concentration affects the rate of reaction  
More particles are crowded within a higher concentration so collisions happen more frequently
