For the following process, determine the change in entropy for the system (AS sys), the surrounding (A.S sys), and the universe (AS univ). Then identify the process as a spontaneous process, a nonspontaneous process, or an equilibrium process at the specified temperature. (Assume that the thermodynamic data will not vary with temperature.) PC13(1) PC13(g) at 61.2C So J K mol AS sys kJ mol AS surr -319.7 217.1 -288.07 J K mol . 311.7 J K mal
