Actual yield/ theoretical yield x 100
Mass of atoms in useful product/ Total mass of reactants x100
Mass of atoms in producy / Total mass of waste x 100
What are the problems associated with developing renewable feedstocks from plants
Plants aren't renewable.
It uses up a lot of land that is needed for other things
It damages the environment because habitat will be cleared to get the pants
fertilizers are needed which use a lot of energy to make

catalysts and feedstock
waste and products
Bulk chemicals and fine chemicals
industrial chemicals and cosmetic chemicals
How does reducing the activation energy affect the reaction?
Speeds up reaction
Allows reaction to take place at a lower temperature
