In a reactor two stream are entering, one with N2 at 10 atm and 27^oC, and another with O2 at 10 atm and 0^oC, producing NO, NO2, NO3, and O2 at 10 atm and 23^oC, what are the total degrees of freedom?(a) 12(b) 17(c) 19(d) 21 |

Answer» Correct option is (c) 19 Easy explanation: Total species = 1 + 1 + 4 = 6, total stream flows = 3, stream pressures = 3, stream temperatures = 3, heat released = 1, and extent of reaction = 3, => degrees of freedom = 6 + 3 + 3 + 3 + 1 + 3 = 19. |
