The energy of an electron present in Bohr's second orbit of hydrogen atom is
Options
- A-1312 ~J atom ⁻¹
- B-328 ~kJ ~mol ⁻¹
- C-328 ~J ~mol ⁻¹
- D-164 ~kJ ~mol ⁻¹
Correct answer
B. -328 ~kJ ~mol ⁻¹
Step-by-step solution
For Bohr's second orbit aligned E_n & = -1312 n^2 ~kJ ~mol ⁻¹= -1312 2^2 & =-328 ~kJ ~mol ⁻¹ aligned
