Title: Yield
Post by: marywaly on April 17, 2022, 11:33:17 PM

In one of my chem eng classes, we calculate the yield of carbon-based products based on the carbon-based reactants.

When there's only one carbon-containing reactant, call it i, the yield of a product k is:

      Y_k=[(n_k)_out-(n_k)_in]/(n_i)_in×(v_i)/(v_k)


where n is the number of moles, v is the stoichiometric coefficient, "in" refers to the inlet stream and "out" refers to the outlet stream.


To my understanding, this equation only works when there's only one carbon-containing reactant, i, that all carbon-containing products originate from.
So, how would the yield of a carbon-based product be calculated in the case of there being more than just one carbon-based reactant that it comes from?

Should be relatively easy to derive from the reaction stoichiometry, after taking into account what is the limiting reagent.
