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
