1
Q
Activation energy
A
The minimum energy required to start a reaction by the breaking of bonds.
2
Q
Catalyst
A
A substance that increases the rate of a chemical reaction without being used up in the process; a catalyst provide an alternative route for the reaction with lower activation energy.
3
Q
Economical benefits of using catalysts
A
Saves energy costs as reactions can now occur in:
- lower temperatures
- low pressures
4
Q
Pollution control benefits of using catalysts
A
- Reduces CO2 emission/ greenhouse emissions
- Reduces the amount of fuel burnt
5
Q
Sustainability benefits for using catalysts
A
- Less waste produced due to higher atom economy
- reaction can take place with less toxic solvents
