QUESTION 5 The reaction Alg) →B(g) is spontaneous under standard conditions. Which of the following statements...
The reaction A(g) B(g) is spontaneous under standard conditions. Which of the following statements are 1. The reaction B(g) → Alg) is nonspontaneous under standard conditions. II. Alg) will be completely converted to B(g) if sufficient time is allowed. III. Alg) will be completely converted to B(g) rapidly. A. I. only B. I. and II. only C. I., II. and III. D.I. and III. only E. II. only F. III. only
Under what conditions will the following reaction be spontaneous? SO2(g) + Cl2(g) → SO2Cl2(g) The following information may be important: ΔHºf SO2(g) = -296.8 kJ/mol, ΔHºf SO2Cl2(g) = 364.0 kJ/mol low temperatures high temperatures always spontaneous never spontaneous
QUESTION 23 Which of the following statements is incorrect? a. A spontaneous process occurs under specified conditions without outside intervention. Ob. AGsys --TASuniv c. A nonspontaneous process occurs only if the surroundings continuously supply energy to the system. d. The relationship between AGⓇ and K at 25°C is: if K< 1, AG° <0. e. A spontaneous change may be exothermic or endothermic.
Under the conditions shown below for the following reaction. Fe2O3(s) + 3 CO(g) - 2 Fe(s) + 3 CO2(g) AG° = -28.0 kJ P(CO) - 3.1 atm, P(CO2) - 1.7 atm Calculate Arxn at 298 K, and indicate if the reaction is more or less spontaneous under these conditions than under standard conditions? -4.5 kJ, more spontaneous than under standard conditions None of these -4.5 kJ, less spontaneous than under standard conditions -23.5 kJ, more spontaneous than under standard conditions...
