The rate constant, also known as the reaction rate constant, is a proportionality constant that relates the rate of a chemical reaction to the concentrations of the reactants. It is typically denoted by the symbol k and has units of inverse time (e.g., s^-1, min^-1, etc.). The value of the rate constant depends on a…
A rate law is an equation that describes how the rate of a chemical reaction depends on the concentrations of the reactants. It is also known as the rate equation or the rate expression. The general form of a rate law is: Rate = k [A]^m [B]^n Where: The orders m and n are usually…
Chemical reactions can occur at different rates, depending on several factors such as temperature, concentration of reactants, the presence of a catalyst, surface area of reactants, and the nature of the reactants. The rate of a chemical reaction is defined as the change in concentration of reactants or products per unit time. The rate of…
Corrosion is the gradual degradation of a material due to a chemical reaction with its environment. It is a natural process that occurs in materials such as metals, ceramics, and polymers, and can lead to the loss of mechanical strength, structural integrity, and even aesthetic appearance of the material. Corrosion can occur in many different…
Batteries are devices that convert stored chemical energy into electrical energy. There are two main types of batteries: primary and secondary. Primary batteries are non-rechargeable batteries that are designed to be used once and then discarded. They are commonly used in low-drain devices such as flashlights, remote controls, and smoke detectors. Primary batteries have a…
Equivalent conductivity and molar conductivity are both measures of the ability of an electrolyte solution to conduct electricity. Equivalent conductivity is the conductivity of a solution containing one equivalent of the electrolyte, which is the amount of the electrolyte that carries one mole of positive or negative charge. It is usually denoted by the symbol…
Electrolytic conductance refers to the ability of an electrolyte solution to conduct electric current. Electrolytes are substances that dissociate into ions when they dissolve in water, and these ions can move freely through the solution and carry electric charge. The conductance of an electrolyte solution depends on several factors, including the concentration of ions in…
Faraday’s laws of electrolysis are two fundamental laws that describe the quantitative relationship between the amount of electric charge passed through an electrolytic cell and the amount of chemical change that occurs during electrolysis. These laws were developed by the British scientist Michael Faraday in the early 19th century. Faraday’s First Law of Electrolysis states…
A galvanic cell, also known as a voltaic cell, is an electrochemical cell that converts chemical energy into electrical energy. The cell consists of two electrodes, each with a different reduction potential, that are connected by an electrolyte. The potential difference between the two electrodes is known as the cell potential or electromotive force (EMF)…
Electrochemical work is the work done by an electrochemical system, which involves the conversion of chemical energy to electrical energy, or vice versa. In an electrochemical cell, the flow of electrons from one electrode to another generates electrical energy, which can be used to do work. The electrochemical work is typically measured in units of…
