Changes in rate of reaction Flashcards
1
Q
Collision theory definition
A
for a chemical reaction to occur the particles must collide with sufficient activation energy
2
Q
When is rate of reaction fastest and why
A
at the start, steepest line - highest concentration of reactant particles, highest frequency of collisions, more product forms per unit of time
3
Q
When is rate of reaction slowing down and why
A
in the middle, line is curving more - lower concentration of reactant particles, lower frequency of collisions, less product forms per unit of time
4
Q
When does rate of reaction stop and why
A
at the end, line levels off - one of the reactant particles has been used up, limiting reactant
