Is enthalpy extensive

WebFeb 15, 2024 · Enthalpy is an extensive property because it depends upon the amount of substances present in the system. Larger the amount of the substance, larger is the value of H. Enthalpy of a system is a state function. It depends upon the state variables (T, P, V, n). When a system undergoes a physical or a chemical change, its enthalpy also changes. WebThe enthalpy changes for many types of chemical and physical processes are available in the reference literature, including those for combustion reactions, phase transitions, and formation reactions. As we discuss these quantities, it is important to pay attention to the extensive nature of enthalpy and
