C5.2.2 - Temperature and reaction rate Flashcards
1
Q
A reaction can only happen if:
A
- reactant particles collide with each other, and
- the colliding particles have enough energy to react
2
Q
What is a successful collision?
A
A collision between 2 particles with enough energy for a reaction to happen
3
Q
As the temperature of a reaction mixture increases…
A
- the particles move quicker so they collide more often
- a greater proportion of the colliding particles have the activation energy or more
4
Q
The greater the rate of successful reaction…
A
the greater the rate of reaction
5
Q
What is relationship between the rate of reaction to the reaction time?
A
The rate of reaction is inversely proportional to the reaction time
6
Q
What is the reaction time?
A
Duration of a reaction from the start to the end
