    Could anyone explain to me how a reaction can have a high percentage yield but a low atom economy? I understand it but can only seem to explain it in a load of rambling that won't really make sense to any examiners...

    Also - What are the benefits to society of a high atom economy?

    Thanks again!

    You can have a reaction which gives a good yield of the desired product but also has lots of useless by-products

    for example: Na2CO3 + 2HCl ---> 2NaCl + CO2 + H2O you can obtain NaCl in 100% yield but you're still going to lose mass in the CO2 and H2O, and atom economy is bass based

    benefits to society? less waste and higher efficiency I guess?
