Question

please explain me how Kc value comes and how to take the values for Kc.​

Answer 1

HEY DEAR

Your answer is here --->

kc is equilibrium constant whose value can be taken in the form of concentrations of only gaseous products and reactants.

You just have to write the ratio of concentrations of the gaseous products and gaseous reactants raised to the power of their respective coefficients. like in this example, gaseous H2O concentrations expressed in mol /L is written with a power of 2 ( which is its coefficient) . divided by concentrations of gaseous H2 and O2 with their coefficients.

But remember that the concentrations of solids or liquids are taken as unity (1) by convention.

If you still have any doubt, you can ask me . ..
