Systems that facilitates this movement of data between devices or end-points are called data communication network. There are 5 components of a data communication network which are data, sender, receiver, transmission medium and protocol.
Molarity (M): Molarity is defined as the number of moles of solute per litter of solution. That is, Here, W = weight of solute. M = molecular mass of solute V = volume of solution Molality (m): It is defined as the number of moles of solute per kg of solvent. …

For the simple second order reaction 2A→product, we know the rate constant is given by, For half life, and Hence, as k is a constant, Thus, the half life of a second order reaction is inversely proportional to its initial concentration.
2A → Productinitial concentration : a molL-1 → 0final concentration (t=t) : (a-x) molL-1 → x …
Derive an expression for the rate constant of 2nd reaction of the type, 2A→product. Read More »
Let us consider a first order reaction, A → product Suppose at the beginning of the reaction, that is, when t=0, the concentration of A is amolL and when t=t, the concentration of A is (a-x)molL. For a first order reaction, the rate of reaction, where k is the rate constant. integrating, Here, c is the …

Order: Order of a reaction is defined by the number of atoms or molecules, whose concentration change during the reaction and determine the rate of the reaction. For example, It is a first order reaction. It is a second order reaction. Molecularity: The molecularity of an elementary reaction is defined as the number of reactant …
