Equilibrium Constant Calculator: Do you need to calculate the equilibrium constant of a reaction? Take a look on this page if that's the case. The handy calculator offered here accepts the molar concentrations of the reactants and products to quickly calculate the equilibrium constants. In the sections below, go over the simple steps, equilibrium constant equation, and solved examples.

## What is Equilibrium Constant?

In a reversible reaction, both forward and reverse reactions happen at the same time. After a particular amount of time, an equilibrium is reached in which the rate of reactants becoming products equals the rate of products becoming reactants. The reaction is thought to be constant at this point in time. a[A] + b[B] ⇌ c[C] + d[D] is an example of a reversible reaction.

The equilibrium constant is independent of the reactant and product concentrations at the start. Temperature, solvent, and ionic strength all play a significant role.

### Equilibrium Constant Equation

The equilibrium constant of a chemical process connects all of the reaction's species. The equation for the equilibrium constant is as follows K = ([C]c * [D]d)/([B]b * [A]a)

• Where, [A], [B] = molar concentrations of the reactants
• [C], [D] = molar concentrations of the products
• K = equilibrium constant
• Kc = conentration

Both the reactants' and products' partial pressures affect Kp. If K > 1, the equilibrium is in favour of the products and if K < 1, the equilibrium is in favour of the reactants. If K = 1, the combination is in equilibrium and contains similar amounts of both reactants and products.

### How to Calculate Equilibrium Constant?

The steps to calculate the equilibrium constant of a chemical reaction is explained below. If you follow them, you'll get instant results.

• Step 1: Get the initial concentrations of the reactants and products, as well as their coefficients.
• Step 2: For all the products and reactants, calculate the molar concentration to the power of the coefficient.
• Step 3: Multiply the product and reactant values in the same way.
• Step 4: To find the equilibrium constant value, divide the product multiplication by the reactants.
