C3 - Percentage yield and atom economy

HideShow resource information
What can we use to work out the predicted yield of the reaction?
The relative formula mass calculations
1 of 5
What is the formula of working out percentage yield?
(actual yield / predicted yield ) x 100
2 of 5
Why do industrial processes need to have a high percentage yield?
So that they reduce the amount of reactants wasted which is wasteful and costly, and reduce their costs by ensuring that enough reactants are used as too little reduces the amount of product
3 of 5
What is the formula of working out atom economy?
mass of atoms in desired product / mass of reactants
4 of 5
Why does industry want high as possible atom economy?
To reduce the production of wasteful, unwanted products which increases costs. Also to make the process more sustainable by making better use of the reactants, so that conserving raw materials and avoiding the need to get rid of wasted products
