Dehydrating sulphuric acid with heat is a common industrial process. It is done by heating it to temperatures above 300°C (572°F). This causes the sulphuric acid to rapidly lose its water content, drying it out and leaving behind a dense, anhydrous (water-free) form of the acid. The dehydrated acid is commonly used in the production …

The industrial preparation of sulphuric acid involves the oxidation of sulphur dioxide with oxygen in the presence of a catalyst. This process is known as the contact process. The reaction takes place in a series of steps. Sulphur dioxide is produced by burning sulphur or by the catalytic oxidation of sulphur compounds. The sulphur dioxide …
Sulphuric acid is a strong mineral acid with the molecular formula H2SO4. It is a highly corrosive acid and is an important industrial chemical, used in the production of fertilizers, explosives, and other chemical products. It is also used in car batteries and to clean metal surfaces.
Catalyst is a substance that can facilitate the reaction rate of a chemical reaction without being consumed or participating in the reaction itself. Chemical equilibrium is a state of balance between the reactants and the products of a chemical reaction. This balance is maintained by the forward and backward reactions occurring at the same rate.
Endothermic reactions are reactions that require energy to occur. This energy can be in the form of heat, which is the most common type of energy used to drive reactions. At equilibrium, the amount of energy being released by the reaction is equal to the amount of energy being absorbed. As a result, endothermic reactions …

Pressure is a measure of the force exerted on a given area, and is typically expressed in units of atmospheres (atm). Chemical equilibrium is a state in which the concentrations of reactants and products in a chemical reaction remain constant over time. This means that the forward and reverse reactions are occurring at the same …

The concentration of the equilibrium haber process will have an effect on the rate of the reaction. If the concentration of reactants is increased, then the rate of the reaction will be faster. Conversely, if the concentration of reactants is decreased, then the rate of the reaction will be slower. The equilibrium haber process is …

Le Chatelier’s principle states that when a system at equilibrium is disturbed by a change in temperature, pressure, or concentration of a counteract the change and restore equilibrium.
Chemical equilibrium is a state of balance between the forward and reverse reactions in a chemical reaction. At this point, the concentrations of the reactants and products remain constant, and the rate of the reaction is equal in both directions. A reaction at equilibrium can be shifted by an external change in temperature, pressure, or …
