### Nitrogen and oxygen react to form nitrous oxide as: 2 N2 (g) + O2 (g) ⇌ 2 N2O (g) Of a mixture of 0.482 mol N2 and 0.933 mol O2 is placed in a reaction vessel of 10.0 L and allowed to from N2O at a temperature for which Kc = 2.0 X 10-37, what will be the composition of the equilibrium mixture?

The given equation is: 2 N2 (g) + O2 (g) ⇌ 2 N2O (g) Therefore the equilibrium constant Kc, will be given as: Kc = [N2O] 2 / [N2] 2 [O2] Initial molar concentrations are: [N2] = 0.482 mol / 10.0 L = 0.0482 mol L-1 [O2] = 0.933 mol ...

### An equilibrium system for the reaction between hydrogen and iodine to give hydrogen iodide at 670 K in a % litre flask contains 0.4 mole of hydrogen, 0.4 mole of iodine and 2.4 moles of hydrogen iodide. Calculate equilibrium constant.

Reaction will be given as: H2 (g) + I2 (g) = 2 HI (g) Therefore, the equilibrium constant K will be given as: K = [HI] 2 / [H2] [I2] The molar concentrations of the species at equilibrium are: [H2] = 0.4 / 5 = 0.08 mol L-1 [I2] = 0.4 ...

### What are the characteristics of Equilibrium Constant?

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 ...

### What are the applications of the Equilibrium Constant?

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 ...

### What are the different types of Chemical Equilibria?

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 ...

### What is Stoichiometric Coefficient?

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, ...

### Derive the relationship between Kp and Kc

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 ...

### Explain the law of Chemical Equilibrium and Equilibrium Constant?

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 ...
