For a certain reaction, DGq = -45 kJ/mol and DHq = -90 kJ/mol at 0°C. What is the minimum temperature at which the reaction will become spontaneous if DHq and DSq are independent of temperature?
  • a)
    273 K
  • b)
    298 K
  • c)
    546 K
  • d)
    596 K
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
For a certain reaction, DGq = -45 kJ/mol and DHq = -90 kJ/mol at 0°...
DGq = -45 KJ/mol
DHq = -90 KJ/mol
T = 273 °K
Using the formula,
DGq = DHq – TDS
-45 = -90 – 273 DS
DS = 0.164
Now since DHq and DSq are independent,
T2 = DH/DS = 45/0.164 = 273°K
Required Temp = 273 + 273 = 546°K
