54. During a spontaneous chemical reaction, it is found that ASsys < 0. This means a. AS surt < 0 and its magnitude is < ASsys. b. AS sur < 0 and its magnitude is > ASsys. AS surr > 0 and its magnitude is < ASsys. ASgurr > 0 and its magnitude is > ASsys. an error has been made, because Ssys > 0 by necessity for a spontaneous process.
4) For a chemical reaction to be spontaneous for standard conditions, which of the following must be true? a) AS rxn < 0 b) AS rxn > 0 c) AGºrx < 0 d) Both a and c e) Both b and c
4) For a chemical reaction to be spontaneous for standard conditions, which of the following must be true? a) AS rxn <0 b) AS nu>0 c) AGO < 0 d) Both a and c e) Both b and c
The exothermic reaction, A--> has AG<0. Which of the following statements are true AH<0 for the reaction AS must be greater than zero AS could be greater than or less than than zero the reaction is spontaneous in the reverse direction
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
In a given process A->B, it is found that AG < 0 and AH>0. Which of the following statements are true The process is spontaneous in the forward directon The process is exothermic As for the process must be less than zero As for the process could be either less than zero or greater than zero
Question 11 Which of the following would indicate a spontaneous Redox reaction? O A. Eo = +0.010 O B.AGO = -23.2kJ O C. Kc = 9.16 X 10-6 O D. both "A" and "B" O E. both "A" and "C" D Question 12 Which of the following indicates a reaction that is always non-spontaneous? O AH<0 & ASCO AH<0 & AS>0 O AH>0 & ASCO O AH>0 & AS>0 none of these indicate non-spontaneity Question 13 Which of the following...
