Question

If true enter $1$, else enter $0$.
The yield of product in a reaction is always equal to the theoretical yield.

• A. 0

Answer 1

The correct option is A 0

A reaction should theoretically produce as much of the product as the stoichiometric ratio of product to the limiting reagent suggests. This number can be calculated and is called the theoretical yield. However, the amount of product actually produced by the reaction will usually be less than the theoretical yield and is referred to as the actual yield. This is because often reactions have "side reactions" that compete for reactants and produce undesired products. To evaluate the efficiency of the reaction, chemists compare the theoretical and actual yields by calculating the percent yield of a reaction:

$\text{Percent yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100$
