QUESTION 3 A certain constant-pressure reaction is barely nonspontaneous at 45 oC. The entropy change for the reaction is 78 J/L. Estimate the AH
The entropy change for a certain nonspontaneous reaction at 85 ∘C is 154 J/K . Is the reaction endothermic or exothermic? What is the minimum value of ΔH (in kJ) for the reaction?
Another chemist has found that a particular constant- pressure reaction is barely spontaneous at 390 K. The enthalpy change for the reaction is +23.700 J. Estimate delta S for the reaction. 1 greater than 61 J/K 2 less than 61 J/K 3 Greater than 16.5J/K 4 Less than 16.5 J/K
At a constant pressure of 3.00 atm what is the enthalpy change AH for a reaction where the internal energy change AE is 58.0 kJ and the volume increase is 12.6 L? (1 L-atm 101.325 J.) 61.8 kJ 76.9 kJ 39.1 kJ 54.2 kJ
Determine the change in entropy for the following chemical reaction occurring at standard pressure and the stated temperature: 2H2(g)+O2(g)→2H2O (l) S°[H2 (g)]=130.7 J/mol·K, S°[O2 (g)]=205.1 J/mol·K, and S°[H2O (l)]=69.91 J/mol·K
spontaneous or nonspontaneous spontaneous or nonspontaneous spontaneous or nonspontaneous Consider the following reaction: CACO3(s) CaO (s) + CO2 (g). Estimate AG for this reaction at each of the following temperatures. (Assume that AH° and AS do not change too much within the given temperature range.) Part A 290 K Part B 1095 K Part C 1475 K
M14. For a particular reaction, the enthalpy change is AH° = +100 kJ/mol and the entropy change is AS° = + 100 J/mol K. What is the equilibrium constant at 300 K?
The change in Gibbs energy of a certain constant-pressure is found to fit the expression AG/J = -85.40 + 36.5 (T/K) where K is Kelvin temperature unit. i) Calculate the value of AS for the process and ii) AH for the process. (Hint: use the Helmholtz Equation)

6) When a spontaneou s, endothermic reaction occurs at constant temperature and pressure, the entropy change of the surroundings is: a) impossible to tell b) positive c) negative d) zero a) ΔG > 0 One finds that the equilibrium constant for a particular reaction increases with increasing temperature. Assuming that the standard reaction enthalpy and entropy are temperature independent, this means that: a) The standard reaction enthalpy is less than zero 8) b) The standard reaction entropy is greater than...
