C5.2.2 - Temperature And Reaction Rate Flashcards
What conditions must be met for a reaction to start?
The reactant particles have to collide with each other
The colliding particles have enough energy to react
What do you call a particle collision which leads to a reaction?
A successful collision
Why might a collision not be successful?
The particles colliding have less energy than the activation energy
What happens to the particles as the temperature of a reaction mixture increases?
The particles move quicker, so more chance of collision
A greater proportion of the particles have the required activation energy
What is the relationship between reaction time and rate of reaction
They are inversely proportional
Show the equation describing the relationship between reaction time and rate of reaction.
1 / reaction time
Is proportional to
Rate of reaction
What happens to the reaction time as the temperature increases?
It decreases
