Which statements are true? O ASsys = -ASurr for ice melting at room temperature. O All other statements are all false. O The second law of themodynamics states that the entropy of a reaction (ASrxn) must always be positive for a spontaneous process. O The standard molar entropy of an element is 0 J/(mol K) at 25°C.
