Atom economy of reaction 1 = 100% ((64.5/ 64.5)*100) atom economy of reaction 2 = 78.18% (64.5/64.5+18)*100. Mass of reactants = mass of useful products = 100% atom economy. Gcse chemistry;atom economy;yield;aqa;edexcel;revision created date:
As Shown Below This Reaction Has Only 50% Atom Economy.
Short answer please caculate the atom economy for the reaction below. In terms of atom economy, which method is preferable. The answer is generally because the other product is also useful and can be sold.
Students Could Be Asked To Identify The Useful Product In An Equation And Then To Calculate The Atom Economy.
Trost has begun to change the way in which chemists measure the efficiency of the reactions they design.” atom economy answers the basic question, “how much of what you put into your pot ends up in your product?” (6). Along with the percentage yield, atom economy is used to analyse the efficiency of reactions; Calculate the atom economy to form copper(ii) oxide from1.
3 This Can Be Done By Taking The Ratio Of The Mass Of The Utilized Atoms (137) To The Total Mass Of The Atoms Of All The Reactants (275) And Multiplying By 100.
Most reactions produce more than one product and very often some of them are not useful; All the reactants are used up to make the direct product. 1calculate the atom economy to form copper(ii) oxide from copper(ii) carbonate.
We Select H2 And O2 To Produce.
Atom economy = !(!)! x 100 = 15.4% c) when choosing which method to use, one factor to consider is the atom economy. The rest of the atoms or mass is wasted. A= for sustainable development/ environmental reasons (1 mark) and economic reasons (1 mark).
Short Answer Please Caculate The Atom Economy For The Reaction Below.
