Three moles of an ideal gas are allowed to expand freely at 300°K from a volume of 100 to 1000 liters. (a) What are the values of AF and A.A for the process? (b) What are the values of AE, AH, AS, q, and w?

For the reaction between carbon dioxide and water in the water gas shift reaction, a) determine the heat of reaction at 25 degrees C, b) determine the heat of reaction as a function of temperature c) determine the Gibbs Free energy of the reaction at 25 degrees C, d) is the reaction spontaneous? e) determine Gibbs Free Energy as a function of temperature f) determine the GIbbs Free Energy of the reaction at 1200 degrees Celcius

A process that takes place so slowly as to be capable of reversing direction in response to an infinitesimally small change in conditions is defined as which of the following terms? O Nonspontaneous process Spontaneous change O Irreversible process Reversible process

Select the statements below that are false, and then think about why they are not true. A chemical reaction is spontaneous if the ASuniv is positive. it is exothermic. the products are lower in energy than the reactants. the AS is positive. Incorrect

Which of the following is true ?  X. Exothermic reactions are spontaneous because formation of products is favored by decrease of free energy of the system  Y. All spontaneous reactions accompanied by increase of entropy of the universum.  Z. All spontaneous reactions accompanied by increase of entropy of the system. * Y only * X, Y and Z * Y and Z only * X only * X and Z only * Z only * X and Y only * none of them

What laws of thermodynamics does the Escher´s drawing violates? Explain.

A certain reaction has negative values for both AH and AS. Therefore, the reaction cannot be spontaneous at any temperature. must be spontaneous at all temperatures. can be spontaneous if the temperature is high enough. Ohas a positive free energy at any temperature. can be spontaneous if the temperature is low enough.
