Can the actual yield be equal to theoretical?
The actual yield for an experimental reaction is not equal to the theoretical yield because of side reactions that occur as well as impurities in the container that might hinder the reaction.
Why is the actual yield not equal to the theoretical yield?
Why Is Actual Yield Different from Theoretical Yield? Usually, the actual yield is lower than the theoretical yield because few reactions truly proceed to completion (i.e., aren’t 100\% efficient) or because not all of the product in a reaction is recovered.
How do you know if a percent yield is reasonable?
Think of percent yield as a grade for the experiment: 90 is great, 70-80 very good, 50-70 good, 40-50 acceptable, 20-40 poor, 5-20 very poor, etc.
What are two reasons why the percent yield may not be 100 for a given reaction?
Reasons for this can include incomplete or competing reactions and loss of sample during recovery. It’s possible for percent yield to be over 100\%, which means more sample was recovered from a reaction than predicted. This can happen when other reactions were occurring that also formed the product.
Is there a possibility that the actual yield will be the same or equal with the theoretical yield If your answer is yes when how it will happen if your answer is no why?
Explanation: Actual yield in a reaction is almost always less than the theoretical yield, primarily because losses of the substances involved may occur anywhere in an experiment. Otherwise, there can be so many possibilities that can be reasoned out depending on the reaction.
What is the difference between theoretical and actual yield?
Amounts of products calculated from the complete reaction of the limiting reagent are called theoretical yields, whereas the amount actually produced of a product is the actual yield. The ratio of actual yield to theoretical yield expressed in percentage is called the percentage yield.
How are actual yield and theoretical yield determined?
When we calculate an amount of product assuming that all the reactant reacts, we calculate the theoretical yield, an amount that is theoretically produced as calculated using the balanced chemical reaction. The amount that is actually produced in a reaction is called the actual yield.
What is meant by actual yield?
An actual yield is the mass of a product actually obtained from the reaction. It is usually less than the theoretical yield. The reasons for this include: incomplete reactions, in which some of the reactants do not react to form the product.
How do you find the actual yield?
The formula to determine actual yield is simple: you multiply the percentage and theoretical yield together.
How is it possible that some of the percent yields are actually greater than 100 \%?
The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage. However, percent yields greater than 100\% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.
What is the importance of percent yield in obtaining theoretical and actual yield?
The percentage yield of a chemical reaction is an important consideration in industrial chemistry. It can be calculated to compare the yield (quantity) of product actually obtained with what could have been obtained in theory, if all of the reactants were converted with no loss or waste.
