Using a tangent to calculate rate of reaction Flashcards
1
Q
Draw the graph for rate of reaction ( vol against time)
A
2
Q
What happens at point 1
A
Initially we get a lot of product formed rapidly= rate of reaction is fast
- because we have a high conc of reactants and a high freq of effective collisions
3
Q
What happens at point 2
A
Overtime the reaction slows down
- because hcl is reacting, the conc of hcl is decreasing. This means that hcl is the limitting reactant so the freq of collisions is reduced
4
Q
What happens at point 3
A
Reaction stops eventually + no more product is formed
- because all of the hcl is reacted and there are no more effective collisions
5
Q
The equation for rate of reaction
A
Rate = vol of gas (cm3) / time (s)
