Different ways of determining limiting reactants

Postby Nicole Shak 1L » Fri Apr 13, 2018 10:49 am

From lecture and discussion, it seems that there are multiple ways of determining the limiting reactant. Is there one way that is best? For example, converting both reactants into moles of a product of an equation and seeing which one is less? Or comparing the results in grams? Or choosing one reactant to convert into and seeing which reactant is in excess?

Honestly you can do whatever works best for you. Personally I calculate the mass of the product for both reactants and compare which one is larger because typically after finding the limiting reactant you are asked to find the theoretical yield and this way you have already done that calculation. Sometimes though I prefer to find the moles of each reactant and compare based on the ratios of reactants needed.

The best way is probably to get the moles of the ingredient and divide them by the coefficient in front of them in the chemical equation, then compare which number is the smallest to determine which is the limiting reactant
