Topic 8 - Rate of Reaction Flashcards
1
Q
Rate of Reaction
A
the rate of change in the concentration of reagents/products
units: mol/dm3/s1
2
Q
Frequency of Collisions
A
number of collisions per second
3
Q
Effective Collisions
A
collisions between reagent particles with the correct orientation and with sufficient energy (Ea)
leads to a reaction taking place
4
Q
Activation Energy
A
minimum amount of energy required for a collision to be effective
used to break bonds in reagents
5
Q
Boltzmann Distribution
A
graphical way of showing the distribution of energies of particles at a given temperature
5
Q
Catalysis
A
change a reaction’s mechanism and lower the activation energy required
5
Q
Enzyme
A
a biological catalyst (protein)
