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
3) For a chemical reaction to be spontaneous for standard conditions, which of the following must be true? a) AS rx > 0 b) AS rx c) AGºrx < 0 d) Both a and c e) Both b and c
urgent 3) For a chemical reaction to be spontaneous for standard conditions, which of the following must be true? a) AS r> 0 b) AS m 0 c) AGºrx < 0 d) Both a and e) Both b and c
on For a chemical reaction that is not spontaneous, it is found that ASys O. Which of the following could be true? < 0 and its magnitude is less than Δ5w Sur>0 and its magnitude is less than ASys ASur 0 and its magnitude is greater than ASsy Surr > 0 and its magnitude is greater than as,ys. ASuniv>0
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.
QUESTIONS At constant pressure and temperature, which statement is true? A. All reactions for which AH<0 are spontaneous B. All reactions for which ASKO are spontaneous. C. All reactions for which AG<0 are spontaneous. D. All reactions for which K> 1 are spontaneous.
True or False or short answer. You must provide reasoning. a. If DSsys <0 for a spontaneous process, then a smaller positive change in Assurr must occur. b. The combustion of ethane is spontaneous, but Dsn is -620.21 J/K. Explain why this does not violate the second law of thermodynamics.
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
For a reaction with AG < 0, which statement is true? Select one: a. Rate is first orders o b. The reaction is endothermic Oc. Keq 0 O d. Keq > 0 e. The reaction is exothermic
If AG < 0 for a reaction, which of the following is/are true? Select all that apply. There will be no net change in the amounts of reactants or products. The reaction is spontaneous in the forward direction. The reaction is spontaneous in the reverse direction. The reaction is at equilibrium. The reaction will proceed to form more products. The reaction will proceed to form more reactants.
