Endothermic Reactions and their Equations

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. In these reactions, the products have a higher energy level than the reactants, and the change in enthalpy (∆H) is positive. Let's look at the equations for the given endothermic reactions:

a) 2SO2 + O2 → 2SO3; ∆H > 0 - This equation represents the reaction between sulfur dioxide (SO2) and oxygen (O2) to form sulfur trioxide (SO3). - The reaction is endothermic, meaning it requires energy input to occur. - The positive value of ∆H indicates that the reaction absorbs heat from the surroundings. - The reaction is commonly known as the formation of sulfuric acid.

b) 2NO2 → N2O4; ∆H > 0 - This equation represents the reaction between nitrogen dioxide (NO2) to form dinitrogen tetroxide (N2O4). - The reaction is endothermic, meaning it requires energy input to occur. - The positive value of ∆H indicates that the reaction absorbs heat from the surroundings. - The reaction is commonly known as the dimerization of nitrogen dioxide.

Please note that the values of ∆H mentioned above are general representations of the reactions and may vary depending on the specific conditions of the reaction.
