enthalpy a state function. Fill in the blank: 4. For a change that takes place at constant pressure, the heat change for system is known as the change in 5. If a reaction is endothermic, but also spontaneous, what must the sign c AS be? 6. If a reaction is exothermic and it goes to an increased state of disorder, wil be spontaneous or non-spontaneous? What is the si of AG? 7. A) In the laboratory you are performing an experiment and you note that F is given off. What is the sign for the change in enthalpy of this reaction? B) Is the potential energy of the reactants lesser or greater than the poten energy of the products? C) You note that the reaction is spontaneous. Just from this information, c you determine the sign of the change in entropy, and if so, what is it?
