How to find equilibrium constant with concentrations?

Now that you have the general idea of how to determine the value of the equilibrium constant at any temperature, let’s determine the value of the equilibrium constant at a specific temperature. We also need to know the concentrations of the reactants and products at that temperature in order to do so. To do this, we will create a spreadsheet that will allow us to quickly vary the temperatures and the concentrations.

How to find equilibrium constant from concentrations?

Now, if you want to calculate the equilibrium constant from the concentrations of the various species involved, you need to use the equation: Kc= [A]0/([B]0 × [C]0 × [D]0). The key to solving this problem is to recognize that each of the species you are solving for is the product of the three species that make up the reaction (and thus, the denominator of the equation). For example, the concentration of A is the product

How to find equilibrium constant if concentration?

Now that you have the value of the reaction quotient for each species involved in the reaction, you can find the value of the equilibrium constant using the following equation:

How to find equilibrium constant without concentrations?

Sometimes it is very difficult to know the concentration of the reactants or products in an equilibrium reaction at any given temperature. An example of this is the reaction between hydrogen gas (H2) and oxygen (O2), H2 + O2 → 2H2O. If you have a gas cylinder of hydrogen and a gas cylinder of oxygen, you can measure the number of moles of each gas in each cylinder and calculate the concentration of each gas at any temperature. However, if you have

How to find the equilibrium constant with concentrations?

The equilibrium constant is not, as you might expect, a constant chemical constant. Rather, it is a ratio that measures the ratio of the forward reaction rate to the backward reaction rate. In the forward reaction, species A converts into species B. In the backward reaction, species B converts into species A. The ratio of the rates of reaction is the equilibrium constant. It is often denoted by Keq or Ka.
