4. Gay Lussac`s Law of Gaseous Volumes
In 1808, Gay Lussac gave this law based on his observations. This law states that when gases are produced or combine in a chemical reaction, they do so in a simple ratio by volume given that all the gases are at the same temperature and pressure. This law can be considered as another form of…

3. Law of Multiple Proportions
This law states that if two elements combine to form more than one compound, the masses of these elements in the reaction are in the ratio of small whole numbers. This law was given by Dalton in the year 1803.

2. Law of Definite Proportions
Joseph Proust, a French chemist stated that the proportion of elements by weight in a given compound will always remain exactly the same. In simple terms, we can say that irrespective of its source, origin or its quantity, the per cent composition of elements by weight in a given compound will always remain the same.

1. Law of Conservation of Mass
In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant. Antoine Lavoisier gave this law in the year 1789 based on the data he obtained after carefully studying numerous combustion reactions.

Laws Of Chemical Combination
Chemistry is the study of the transformation of matter from one form to the other. These transformations often occur as a result of the combination of two different types of matter. The combination of different elements to form compounds is governed by certain basic rules. These rules are referred to as laws of chemical combination. There are…

FAQs
1. What is mass law constant?Ans: Mass action law states that a chemical reaction frequency is proportional to the active masses of reacting materials at a constant temperature. Kc is the reaction constant of equilibrium, while Kp is the constant of equilibrium found by applying partial pressure. 2. What are KP and KC?Ans: Kc and…

Relation between Kc, Kp and Kx
K p=K c ( R T ) ∆ n g Kp = Kx . P Δng Where, ∆ n g = moles of gaseous products – moles of gaseous reactants. Kc is the equilibrium constant expressed in terms of the concentration of the reactants/products. Similarly, Kp is the constant in terms of the partial pressures of the substances and…

Representation of the Equilibrium Constant
For a balanced reaction of the type, aA + bB ⇌ cC + dD According to the law of mass action, the constant value obtained by relating equilibrium concentrations of reactants and products is called the equilibrium constant. For the forward reaction, this is given by K c=[ C ] c [ D ] d /…

The Equilibrium Constant (Kc)
The concentration of reactants and products, at equilibrium, are constant at a given temperature. Consider the following simple reversible reaction where A & B are the reactants whereas C & D are the products. A + B ⇌ C + D A mixture of products and reactants in a state of chemical equilibrium is known as an…

Law Of Mass Action
What is the Law of Mass Action? The law of mass action states that the rate of a reaction is proportional to the product of the concentrations of each reactant. This law can be used to explain the behavior exhibited by solutions in dynamic equilibria. The law of mass action also suggests that the ratio of…
