To calculate the dissociation constant for a chemical reaction, you divide the concentrations of the products by the concentration of the reactants raised to the power of their respective stoichiometric coefficients. This gives you the equilibrium constant, which is a measure of how much the reactants form products at equilibrium.

How can one determine the acid dissociation constant (Ka) from the concentration of a solution?
To determine the acid dissociation constant (Ka) from the concentration of a solution, you can measure the concentrations of the acid, its conjugate base, and the equilibrium concentrations of both in the solution. By using these values in the equilibrium expression for the acid dissociation reaction, you can calculate the Ka value.
How to calculate the rate constant for a chemical reaction?
To calculate the rate constant for a chemical reaction, you can use the rate equation and experimental data. The rate constant (k) is determined by dividing the rate of the reaction by the concentration of the reactants raised to their respective orders. This can be done by plotting experimental data and using the slope of the line to find the rate constant.
What are the indicators that can be used to determine dissociation constant?
If you mean chemical indicators as used for indicating pH and reaction end-points, the answer is none, unless you are only looking for a very rough estimate at dissociation constant. The error involved in using an indicator would be very large. If you used an indicator, choice would depend on the compound, what its dissociation constant was and what it dissociated to.

Factors affecting dissociation constant of acid?
The dissociation constant of an acid is affected by factors such as temperature, solvent, and ionic strength of the solution. Increasing temperature generally leads to higher dissociation constants, while changes in solvent polarity can also impact the dissociation constant. Additionally, the presence of other ions in the solution can affect the dissociation constant by influencing the equilibrium position of the acid dissociation reaction.
