Which statement(s) O State functions are path independent. State functions are the opposite of path functions. State functions are path functions about state functions is correct?

Calulate the eneray change of a system

A certain reaction has Ho = -66.40 kJ and So = 0.00 J/K.(a) Is this reaction exothermic, endothermic or isothermic (neither)?This reaction is.(b) Does this reaction lead to a decrease, an increase, or no change in the degree of disorder in the system?This reaction leads to in the disorder of the system.(c) Calculate Go for this reaction at 298 K. If this value is less than 1 kJ/mol then enter 0 in the answer box.Go =  kJ.(d) Is this reaction spontaneous, nonspontaneous, or near equilibrium under standard conditions at 298 K?This reaction is under these conditions.

Which of the following is not a state function? a. Т O b. H O c. S O d. None; they are all state functions. O e. U

Arrange the states of matter in order of decreasing entropy.

At - 16.4 °C the pressure equilibrium constant K, = 7.4 for a certain reaction. Here are some facts about the reaction: • The constant pressure molar heat capacity C, = 1.04 J'mol. K. %3D • The reaction is endothermic. • If the reaction is run at constant pressure, the volume increases by 13.%. Yes. Using these facts, can you calculate K, at - 33. °C? O No. If you said yes, then enter your answer at right. Round it to 2 significant digits. Yes, and K, will be bigger. If you said no, can you at least decide whether K, at - 33. °C will be bigger or smaller than K, at - 16.4 °C? Yes, and K, will be smaller. No.

4. Which of the following is always true for an exothermic process? A. qsys > 0, ASsurr 0 C. qsys 0, ASsurr > 0

The change of energy of a thermodynamic system is equal to: the amount of work done to or by the system and the amount of heat gained or lost. O the amount of heat gained or lost. O impossible to calculate the change in energy O the amount of work done to or by the system.

4. For a chemical reaction that has a AGº value of +275 kJ/mol, what value must Q have for this system to be at equilibrium? Show all work. 30 281 SAS

Consider the thermodynamic quantities E, 9, and w. Which of these quantities are state functions?
