以平衡化学方程式表示的反应物和产物的相对量通常称为<化学计量比。然而,实际上,反应物并不总是以平衡方程所指示的化学计量的量存在。 在化学反应中,首先消耗掉并限制形成的产物量的反应物是限制性反应物,而另一种物质则成为过量反应物。通常使用过量的一种或多种反应物来确保另一种反应物完全转化为产物。 考虑由...

更新1: Given the relative atomic mass of Fe = 55.8 ; O = 16.0 ; C = 12.0 更新2: Some calculation errors you make: No. of moles of Fe2O3 added = (700 x 1000 x 1000)/159.6 = 4.403 x 10^6 mol It should be 4.386x10^6 mol But nevermind~更新3:...
Hydrogen-water are the primary reactant-product pair in the fuel electrode of reversible solid oxide cells. A different dependence of polarization resistance on pH2O in fuel cell and electrolysis modes has been proven experimentally, revealing different rate-limiting steps in fuel electrodes in these...
The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in reality, the reactants are not always present in the stoichiometric amounts indicated by the balanced equation....

In a chemical reaction, the reactant which gets consumed first, and limits the amount of product formed, is the limiting reactant, while the other substance becomes the excess reactant. An excess of one or more reactants is often used to ensure the complete conversion of the...
