Atom utilization Atom The amount of target product formed utilization ×100 The amount of all products formed stoichiometrically The amount of target product formed ×100% The amount of reactants used
Atom utilization = = The amount of target product formed ╳ 100% The amount of all products formed stoichiometrically The amount of reactants used The amount of target product formed ╳ 100% Atom utilization
原子利用率 目标产物的量 ×100% 按化学计量式所得所有产物的量之和 目标产物的量 ×1009 各反应物的量之和 The two main characteristics of chemical reaction with 100% atom utilization The reactants could be fully utilized, and the resource could be most possibly used economically The waste could be minimized
The two main characteristics of chemical reaction with 100% atom utilization: ✓ The reactants could be fully utilized, and the resource could be most possibly used economically ✓ The waste could be minimized 原子利用率 = 目标产物的量 按化学计量式所得所有产物的量之和 = 目标产物的量 各反应物的量之和 ╳ 100% ╳ 100%
