A route has atom economy 68% and produces useful by-product that can be sold. How does that affect the environmental assessment?
Ethanol + ethanoic acid ? ethyl ethanoate + water. Calculate the atom economy for ethyl ethanoate (desired product). (Use Ar: C = 12, H = 1, O = 16.)
A synthesis route produces 2 g desired product and 6 g waste from a given amount of reactants. What is the atom economy for the desired product?
If a reaction has an atom economy of 25%, what fraction (by mass) of the reactant atoms becomes waste?
Which reaction has the higher atom economy for the desired product NH4NO3: A: NH3 + HNO3 ? NH4NO3 ; B: NH4Cl + AgNO3 ? NH4NO3 + AgCl ?
Two industrial routes produce the same desired product. Route A has atom economy 90%, Route B has atom economy 45%. Assuming similar costs and environmental controls, which route is preferable on atom economy grounds and why?
A chemist reports an atom economy of 95% for producing a fine chemical. Which of the following is a realistic implication?
Which of the following best defines atom economy?
Which of the following best explains why atom economy is different from percentage yield?
For the reaction: 2A ? desired product + B (where B is waste), a chemist increases atom economy by:
Calculate the atom economy for the reaction H2 + Cl2 ? 2HCl.
