NEET Chemistry Question (2024) — Solution

Question

Given below are two statements: Statement I: The Balmer spectral line for H atom with lowest energy is locateld at 5 36 R_H ~cm ^ -1 . ( R _ H = . Rydberg constant ) Statement II: When the temperature of blackbody increases, the maxima of the curve (intensity and wavelength) shifts to shorter wavelength. In the light of the above statements, choose the correct answer from the options given below:

Options

  1. A. Statement I is true but Statement II is false
  2. B. Statement I is false but Statement II is true
  3. C. Both Statement I and Statement II are true
  4. D. Both Statement I and Statement II are false

Answer

C. Both Statement I and Statement II are true

Step-by-step solution

For Balmer series n _1=2 n _2=3 v = 1 =R_H [ 1 n_1^2 - 1 n_2^2 ] v =R_H [ 1 4 - 1 9 ] v = 5 R_H 36 ~cm ^ -1
