Comparing Percentage Yield and Atom Economy | GCSE
Industries must balance high yields with high atom economy for sustainable production.
Can a reaction have 100% yield but low atom economy?
What is Comparing Percentage Yield and Atom Economy | GCSE?
"The evaluation of chemical processes based on both their actual output and their theoretical efficiency."
Calculate the relative formula mass (Mr) of H2O. (H=1, O=16)
Calculate the mass of 0.25 moles of Calcium Carbonate (CaCO3). (Mr=100)
How many moles are in 36g of water? (Mr of H2O = 18)
Which formula is used to calculate the number of moles?
Efficient Chemistry
Percentage Yield: How much product you actually got.
Atom Economy: What percentage of reactants became the DESIRED product.
High Atom Economy: Minimises waste and the need for raw materials.
High Yield: Maximises profit from the reaction.
Sustainability: Even if a yield is 100%, if the atom economy is low, most of the starting material is wasted as unwanted byproducts.
