How to find equilibrium constant without concentrations?

Now that we have covered the basics of the equation, we can return to the question of how to find the value of equilibrium constant without using actual concentrations. The answer is that you can’t. At least not in a straightforward way. In order to solve the equation, we need to know the activities of each component of the system as well as their partial pressure. Determining the activities of each component of the system is generally not an easy task.

How to find equilibrium constant without activities?

The activity of a reaction is a measure of how much energy is transferred during the reaction, which is the product of the reaction’s rate constant and the concentration of each reactant. This means activities are a function of the equilibrium constant, or only in the case of irreversible reactions However, if you are only interested in the ratio of the forward reaction rate to the backward reaction rate, you can work with the equilibrium constant without activities.

How to find equilibrium constant without concentrations and activities?

The key to solving this problem is to express the equilibrium constant in terms of different properties of the reaction. Instead of activities, consider the Gibbs free energy of reaction, ΔG. This is the amount of free energy needed to start the reaction. For an endothermic reaction, ΔG is negative and for an exothermic reaction ΔG is positive. ΔG is temperature independent and is the same for all reactions. Now, ΔG can be expressed as a function of the enthalpy

How to find equilibrium constant without concentrations and activities table?

A very common mistake is to solve the equilibrium constant equation for activity and concentration and use this solution to find the equilibrium constant. If you do this, the result will not be the correct value. The reason is that solving for the activities in the equilibrium constant equation can lead to division by zero.

How to find equilibrium constant without concentrations and activities equation?

When the activity of any chemical species is involved, it is a good idea to use the relationship between chemical potential and activity. Chemical potential is the energy needed to move a single unit of a particular species from one point to another. Using the relationship between chemical potential and activity, we can find the equilibrium constant without activities. This is because the chemical potential of an ideal gas, which is the sum of the enthalpy of the gas (the amount of heat required to transfer a single unit of gas
