What of the following options describes the term "entropy, S"? O a. If a process or reaction is carried out in multiple steps, the sum of the enthalpy changes for these steps is the same as the enthalpy change if the entire reaction was carried out in a single step. O b. An indication that a process is capable of proceeding in a given direction without needing to be driven by an outside source of energy. O c. A thermodynamic function which measures the dispersal of energy amongst the particles in a substance. O d. The substances or material being studied in an experiment. For a chemical reaction, the system is all of the atoms in the substances undergoing the reaction. O e. Everything outside of the system.
