The enthalpy and entropy change for the reaction: are and respectively. The temperature at which the reaction will be in equilibrium is 300 K 285.7 K 273 K 450 K
Multiple Choice Options
- A in NH 3 the atomic dipole and bond dipole are in the opposite directions whereas in NF 3 these are in the same direction
- B in NH 3 as well as in NF 3 the atomic dipole and bond dipole are in the same direction
- C in NH 3 the atomic dipole and bond dipole are in the same direction whereas in NF 3 these are in opposite directions
- D in NH 3 as well as in NF 3 the atomic dipole and bond dipole are in opposite directions.
Step-by-Step Verified Solution
The dipole moment of NF 3 is 0.24 D and of NH 3 is 1.48 D. In NF 3 , the dipole moment vector are aligned in opposite direction to that of the dipole moment vector of lone pair on N�atom which partly cancel out. On the other hand, N�H bonds in NH 3 are in the same direction of dipole moment of the lone pair on N-atom which adds up the new resultant dipole moment.
