Question

q. When the
a hydrogen atom undergoes taansitio
from an energy
level with h = 4 to an energy level with n= 2. Calculate the energy change in KJ/mol in above transition??​

Answer 1

Answer:

246KJ/mol

Explanation:

1312(1/n1² - 1/n2²)

= 1312(1/2² - 1/4²)

=1312(1/4 - 1/16)

= 1312(4 - 1)/16

= 82×3= 246KJ/mol
