b. illegal
c. combustive
d. nonspontaneous
Expert Solution
Step 1
Given,
Temperature, T = 25oC = (25 + 273.15) K = 298.15 K
△Srxn = –386.9 J/K
△Hrxn = 147.5 kJ = 147500 J (1 kJ = 1000 J)
Step 2
The value of △Grxn can be calculated using the Gibb’s free energy formula as :
Since the value of △Grxn is positive, so the reaction will be non-spontaneous.
