The important characteristics of equilibrium constant are discussed below: 1. The equilibrium constant has a definite value for every reaction at a particular temperature. 2. The value of equilibrium constant is independent of the original concentration of reactants. 3. The value of equilibrium constant tells the extent to which a reaction ...

Applications of the equilibrium constant 1. The magnitude of the equilibrium constant : The magnitude of the equilibrium constant K means the extent to which a reaction can proceed i.e. measuring the completion of the reversible reaction. If the value of K is larger, then the equilibrium concentration ...

There are two types of chemical equilibria: 1. Homogeneous equilibrium 2. Heterogeneous equilibrium 1. Homogeneous equilibrium: The equilibrium reactions in which all the reactants and the products are in the same phase are known as homogeneous equilibrium reactions. These are divided into two categories: (a) The number of product molecules is equal ...

Stoichiometric coefficient: The number of molecules of a reactant taking part in a reaction is known as Stoichiometric coefficient. For example: Consider the following equation: aA + bB ⇌ cC + dD In this equation, a, b, c and d are called as Stoichiometric coefficients of the A, B, ...

Relationship between Kp and Kc Consider the following reversible reaction: aA + bB ⇌ cC + dD The equilibrium constant for the reaction expressed in terms of the concentration (mol / litre) may be expressed as: K c = [C] c [D] d / [A] a [B] b If the ...

Norwegian Chemists Waage and Gulberg were the ones who gave us law of mass action. This law of mass action suggest a quantitative relationship between the rates of the reaction and the concentration of the reacting substances. Law of mass action states that: The rate of a ...

The state at which the concentrations of reactants and products do not change with of a chemical reaction is known as chemical equilibrium. When the reactants are mixed together in a vessel, the whole reactants do not completely converted into products. After some time the ...

Mathematically, G = H – TS At constant temperature, ∆G = ∆H - T∆S Hence two factors contribute to the value of free energy ∆G. One is energy factor ∆H and the other is entropy factor T∆S. Both the factors are necessary for calculating the spontaneity of the reaction. The ...

If the free energy change i.e. ∆G of a chemical reaction is positive, the reaction would not proceed. If the free energy change i.e. ∆G of a chemical reaction is negative, the reaction would be spontaneous i.e. feasible. If the free energy change i.e. ∆G ...

Spontaneous reaction is those which proceed at very fast rate. A chemical reaction which is accompanied by evolution of heat is known as exothermic reaction. Spontaneous reactions are also known as exothermic reactions. In the exothermic reactions internal energy change has negative sign at constant ...
