The statement below is given which one of the following names?
“The enthalpy change of a chemical reaction is independent of the route taken between the initial and the final states.”
Consider a process in which a system undergoes a change from some initial thermodynamic state (1) to some final thermodynamic state (2). Suppose that the thermodynamic variables of state are well-characterized for both the initial and final states, but the path (through the variable space) between the two states is not well-characterized. Which of the following quantities associated with the change-of-state process cannot be determined without a detailed specification of path?
