- Atom Economy & Percentage Yield
- Atom Economy
- It's defined as 'the proportion of reactants that are converted into useful products'
- (molecular mass of desired product/sum of molecular masses of all products)x100
- Processes with high atom economy are more efficient and produce less waste
- This is important for sustainable development
- You can have a higher atom economy by...
- Finding a use for the other products
- If possible, do an addition reaction because the molecules add together to form the desired product
- Percentage Yield
- It's defined as 'the actual amount in moles of the product shown as a percentage of the expected yield in moles'
- % yield=(actual amount of product in moles/theoretical amount of product in moles)x100
- You can use ratios to work out the theoretical amount
