product formed in a chemical reaction

Theoretical Yield

Theoretical Yield–(also called predicted yield)

Theoretical Yield–(also called predicted yield) is the amount of product predicted by a stoichiometric calculation.

In other words, if we’re given the amounts of reactants and asked to use stoichiometry to find the mass of a product, then we are finding the theoretical (or predicted ) yield of that product.

For various reasons, when a reaction is carried out in a real physical setting, like a lab or an industrial site, we don’t always get the amount of a product predicted.

Actual yield

For various reasons, when a reaction is carried out in a real physical setting, like a lab or an industrial site, we don’t always get the amount of a product predicted.

Actual yield – the amount of a product that is actually obtained in a reaction.
