Classify each of the statements as true or false. False Truc An exothermic reaction is always spontaneous. The entropy ofa substance increases when a solid melts into a liquid at any temperature. Product formation is never favored in a reaction with a negative AH and a positive AS. For an endothermic reaction, a decrease in temperature results in a decrease in the equilibrium constant. A reaction will have an equilibrium constant that is less than one if AG" for the reaction is positive. Entropy increases as the temperature decreases. Answer Bank 2°C Mostly cloudy A a ENG 01/0

Compare what will happen to the entropy of the whole system in the following two scenarios: A) if the oil molecules are all clumped together and the clump is surrounded by water and B) if the oil molecules are spread out evenly throughout the water, each individual oil molecule surrounded by water?
Which one of the following choices of gaseous molecules is rank ordered correctly from lowest standard molar entropy (left hand side) to highest standard molar entropy (right hand side)? He, Ne, CO, SiH4 SiH4 , CO, Ne, He SiH4 , Ne, CO, He CO, SiH4 , Ne, He
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.
