Reacting moles
WebOne mole of reaction (mol rxn) refers to a reaction unit. In order to define a mole of reaction the chemical equation must be known. In our example the coefficient for CO would … WebJul 18, 2024 · The most useful quantity for counting particles is the mole. So if each coefficient is multiplied by a mole, the balanced chemical equation tells us that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This is the conventional way to interpret any balanced chemical equation.
