The equilibrium concentrations of the species in the reaction A + B ⇋ C + D are 2 , 3 , 10   and   6   mol   L - 1 respectively at 300 K . ∆ G ∘ for the reaction is R   = 2   cal / mol   K
Options
- A- 13 . 73   cal
- B- 1372 . 60   cal
- C- 137 . 26   cal
- D- 1381 . 80   cal
Correct answer
D. - 1381 . 80   cal
