අමාරු රසායනය සුපිරි ලෙස සමත් වීමට තල්ලුව&#3482

There are many guys and girls who are taking Chemistry core courses as compulsory subjects.

Being a Final Year Undergraduate in Chemistry I thought of giving whatever help I can, to somebody with a need. I have seen many students having numerous difficulties with regard to Physical Chemistry and Analytical Chemistry components. You can post your questions here, and since many intellectuals will aggregate in Elakiri, I presume help will be readily available.

I invite each and everyone to post whatever you think will be related to Chemistry, with a proper heading so that anyone can use them as an additional reference material.

Writing Equilibrium Constant Expressions Involving Solids and Liquids

Problem 1 involves calculating some equilibrium concentrations and then a value for Kc. The equation pV = nRT is used to calculate some corresponding (partial) pressures, from which a value for Kp can be calculated. In this calculation the volume remains constant and so the total pressure changes on reaching equilibrium. Finally, the equation Kp = Kc(RT)Dn is used to calculate a value for Kp again, but this time from the value of Kc.

Problem 2 involves calculating the equilibrium molar amounts of reactants and products, and then their partial pressures, from which a value for Kp can be obtained. In this calculation the total pressure remains constant and so the volume changes on reaching equilibrium.


The equilibrium constant expression is the ratio of the concentrations of a reaction at equilibrium. Each equilibrium
constant expression has a constant value known as K, the equilibrium constant. When dealing with partial
pressures, Kp is used, whereas when dealing with concentrations (molarity), Kc is employed as the equilibrium
constant. Reactions containing pure solids and liquids results in heterogeneous reactions in which the
concentrations of the solids and liquids are not considered when writing out the equilibrium constant expressions.
