# What Is Theoretical Yield & How To Calculate It?

In chemistry, you have to understand the reaction kinematics. The reason is that without it, you will never be able to grip over reaction stoichiometry and completion. Also, you cannot understand how to balance chemical equations. This is why the following blog will be a piece of advice for you. We will highlight the importance of theoretical yield in chemical synthesis and use a free theoretical yield calculator. The calculatored.com proposes this online tool and is one of the trusted tools to calculate theoretical yield.

## What Is Theoretical Yield?

In chemistry:

The maximum amount of product that can be formed in a chemical reaction and is estimated manually is called theoretical yield.

The ultimate theoretical yield calculator can be used as a great tool to compute this chemical term with 100% accuracy and in microseconds.

## Theoretical Yield Formula:

If your goal comes up with manual computations, you may use the following equation:

## Steps To Calculate Theoretical Yield:

You need to follow these steps if you are willing to calculate theoretical yield in chemistry:

### Balance the Given Chemical Equation:

It is very important to have an equal number of atoms on both sides of the reaction. For instance, let us consider the example of ammonia formation:

The above reaction is not balanced. If you see on the left side, there are two atoms of nitrogen and hydrogen. But if we look on the right side, we have 1 atom of nitrogen and 3 atoms of hydrogen. Now here the theoretical yield calculator will also give you a non-certain result as the reaction is not balanced. The balanced form of this reaction is as follows:

But if we still look above equation, the number of hydrogen atoms is still not balanced. This is why we multiply the H_3.

### Look For Limited Reagent:

The component of the reaction that will fully react before the other reacting agents are known as the limiting reagent. Given that the amount of this reactant restricts the yield of the product, this is important to determine the theoretical yield.

### Steps:

• Calculate the moles of each reactant in the reaction to determine which one is the limiting reactant. Use each substance’s molar mass to do this.
• Compare the ratio of moles to the final product given the moles of each component. The limiting reagent is the reactant with the most significant ratio.

## Determine Moles of Limiting Reactant:

The next step is the calculation of moles that have reacted in the reaction schemes. And this can be done by using the following equation:

## Use Theoretical Yield Calculator or Formula:

This is the last step that instantly gives you the calculations for the theoretical yield.

## Difference Between Percent and Theoretical Yield:

The percent yield is the ratio of the theoretical and actual yield of a chemical reaction.

Mathematically:

Whereas, the theoretical yield is just on-paper calculations of the yield of a chemical reaction. It is just an estimation because when it comes to practically, there is no surety how much product will be formed after a reaction ends.

## Wrapping It Up:

We hope you may not have to face any trouble while calculating the theoretical yield of a chemical reaction. In case you may feel hassle, start using the best theoretical yield calculator and say bye to your complications.
