Consider the following reaction at constant pressure. Use the information here to determine the value of AS surr at 298 K. Predict whether or not this reaction will be spontaneous at this temperature. N₂(g) +202(g) → 2NO₂(g) AHrxn = +88.4 kJ mol-1 ASsurr = +88.4J K-1 mol-1, reaction is spontaneous Assurr = -88.4J K-1 mol-1, reaction is spontaneous ASsurr = -88.4J K-1 mol-1, reaction is not spontaneous ASsurr = +297 J K-1 mol-1, reaction is spontaneous ⒸASsurr = -297J K-1 mol-1, reaction is not spontaneous
QUESTION 12 Which of the following is false about the second law of thermodynamics? O It is not possible to construct a perpetual motion machine which can work endlessly without the expenditure of energy. O It is impossible to transfer heat from a heat source to a hotter body without doing some work. O t is not possible to take heat from a source and convert all of it into work without losing some of it to a colder reservoir. O The entropy fo the universe is always increasing.
At what temperature will the following reaction become spontaneous?3CO2(g) + 3H2O(l) ® CH3COCH3(g) + 4O2(g) DH = 854.00 kJ/mol and DS = 236.00 J/mol*K 3128. �C 3619. �C 1090. �C 3345. �C

Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction A B с observations Crystallization of a pure compound is spontaneous only below 23. °C. This reaction is spontaneous only above 31. °C but proceeds at a faster rate above 83. °C. The reverse of this reaction is always spontaneous but proceeds faster at temperatures above 108. °C.
