Chemical Reaction Calculator is a predicting products of chemical reactions calculator which makes calculations easy and fun. It is a chemical reaction calculator that is used to calculate the balanced equation and equilibrium constant when a chemical equation is given. Chemical reactions should always be balanced, a balancing chemical equation has same number of atoms on both reactant and product side. Try our chemical reactions calculator (word equation calculator) by editing the default equation and get your problems solved instantly.

Below is given a default equation you can just see how the balancing reaction of that equation is done and equilibrium constant(Kc) is calculated.

## Steps for Chemical Reaction Calculator

Step 1 :

Convert the given word equation into formula equation.

Step 2 :

To balance the given equation: first write the number of different atoms present on left hand side and right hand side of the equation and then add coefficients to balance the equation, so that we have the equal number of atoms of each element on both the reactant(left hand side) and product(right hand side) of the equation.

Step 3 :

To know the equilibrium constant(Kc) of the given chemical reaction. Use the formula: Kc = $\frac{[C]^{c} [D]^{d}}{[A]^{a} [B]^{b}}$

where a,b,c and d = are the numbers in front of the each substances in the chemical reaction

A and B =  are the concentration of reactant.

C and D = are the concentration of product.

## Examples on Chemical Reaction Calculator

1. ### Find the equilibrium constant(Kc) for the chemical equation: Al + O2 -> Al2O3 ?

Step 1 :

Given chemical equation: Al + O2 -> Al2O3

Step 2 :

Atoms on:

Reactants side                Products side

4 x 1---------Al--------2 x 2 = 4

3 x 2---------O--------3 x 2 = 6

4Al + 3O2 -> 2Al2O3

Step 3 :

Equilibrium constant(Kc) = $\frac{[Al_{2}O_{3}]^{2}}{[Al]^{4} [O_{2}]^{3}}$

Balanced equation: 4Al + 3O2 -> 2Al2O3

Equilibrium constant(Kc) = $\frac{[Al_{2}O_{3}]^{2}}{[Al]^{4} [O_{2}]^{3}}$

2. ### Find the equilibrium constant(Kc) for the chemical equation: H2 + I2 -> HI ?

Step 1 :

Given chemical equation: H2 + I2 -> HI

Step 2 :

Atoms on:

Reactants side                Products side

2---------I--------1 x 2 = 2

2--------H--------1 x 2 =2

H2 + I2 -> 2 HI

Step 3 :

Equilibrium constant(Kc) = $\frac{[HI]^{2}}{[H_{2}] [I_{2}]}$

Equilibrium constant(Kc) = $\frac{[HI]^{2}}{[H_{2}] [I_{2}]}$
