The effects of catalysts on rate of reaction

What activation energy

Minimum energy particles must have in order to start a reaction by breaking chemical bonds.

The enthalpy different between reactants and transition state

Whats the transition state

Represents an unstable moment where old bonds are actively breaking and new bonds are forming.

What do catalysts do

Speed up reaction by allowing reaction to take place via an alternative pathway with a lower activation energy than the uncatalysed reaction

How does using catalysts help

They are not used up in reactions and are reusable

Reduces amount of energy needed by chemical industry, reduces need to burn fossil fuels to provide this energy, saves money providing economic benefit.

Reduces CO2 emissions, making chemical industry more sustainable.
