Question

Which situation describes a reaction with a percentage yield of 100%?

Select one:
a. The amounts of reactants initially present are stoichiometric.

b. The product is more than the limiting reagent has the potential to produce.

C. none of them

d. No competing reactions occur and the limiting reagent is fully consumed.

Answer 1

Answer:

C. none of them

Explanation:

When limiting reagent like the name implies is entirely consumed the reaction will not go to stoichiometric completion.

Answer 2

The percentage yield has been given by the ratio of the actual and theoretical yield. The percentage yield can be 100% when the product formed is more than the limiting agent could have produced. Thus, option b is correct.

What is a percentage yield?

A percentage yield is the reaction yield of the chemical reaction that is given in reference to the amount or moles of product formed by the consumption of the reactants.

The percentage yield is estimated as the fraction of the actual yield and theoretical yield multiplied by 100. The actual yield is the experimental yield and if is equivalent to the theoretical yield results in 100%.

The percentage yield can be 100% if the product formed is in more amount or concentration as the limiting agent could have the ability to form.

Therefore, option b. the percentage yield is 100% if the product is more than the limiting reagent could have produced.
