QUESTION 5 For the reaction CH3OH (g) CO(g) + 2 H2(g) Ho-907 kJ and S0-221 J/K. Which of the following best fits this reaction? O a. The reaction is always spontaneous. O b. The reaction is never spontaneous. O c. The reaction is spontaneous only at high temperatures. O d. The reaction is spontaneous only at low temperatures. uestion Completion Status Consider this reaction A(g) + 2B(g) C(g) + D(g) Ho for the reaction is 86.5 kJ/mol and So for the reaction is-15.3 J/moIK. At 298K, what is Go in kJ for the reaction?Explanation / Answer
Q5)
G = H-TS = 90.7-298*221/1000 = 24.842
Since G>0, it is NOT spontanous
G = never spontanous, since G<0
Therefore
H < TS
but TS can never be negative, so assume it is impossible
Q6)
G = H-TS = 86.5 - 298*-15.3/1000 = 91.05
A)
G = H-TS = 90.7-298*221/1000 = 24.874
