The formation of nitrogen dioxide (NO2) from its elemental constituents can be represented by the reaction: N2(g) + 2 O2(g) → 2 NO2(g). The enthalpy change for this reaction indicates that 33.1 kJ/mol of energy is required to form NO2. This value reflects the energy needed to break the bonds in the reactants and form the bonds in the product. Thus, the positive enthalpy change signifies that the reaction is endothermic, necessitating an input of energy for the formation of NO2.
The reaction that shows the formation of CO2 releasing 393.5 kJ/mol is typically represented as the combustion of carbon or hydrocarbons. For example, the reaction for the combustion of carbon can be written as: [ C(s) + O_2(g) \rightarrow CO_2(g) ] This reaction indicates that the formation of one mole of carbon dioxide from solid carbon and oxygen gas releases 393.5 kJ of energy, demonstrating an exothermic process.
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
The reaction that indicates the formation of SO2 releases 296.8 kJ/mol is typically represented as: [ S(s) + O_2(g) \rightarrow SO_2(g) , \Delta H = -296.8 , \text{kJ/mol} ] This notation shows that when one mole of sulfur reacts with one mole of oxygen to form sulfur dioxide, it releases 296.8 kJ of energy, indicating an exothermic reaction.
The reaction that shows the formation of carbon dioxide (CO2) releasing 393.5 kJ/mol is the combustion of carbon in oxygen, represented by the balanced equation: C(s) + O2(g) → CO2(g). This exothermic reaction indicates that when one mole of carbon reacts with oxygen to form carbon dioxide, it releases 393.5 kJ of energy. This energy release is a key factor in various applications, including combustion engines and the generation of heat in industrial processes.
