Question

Quizplus · Accepted Answer

The energy of the radiation required to excite an atom from the n₁=1 orbit to the n₂=4 orbit is given by the equation:E = hc/λ = hcR(1/n₁² - 1/n₂²)where h is Planck's constant, c is the speed of light, λ is the wavelength of the radiation, and R is the Rydberg constant.Substituting the values of h, c, R, n₁, and n₂ into the equation, we get:E = (6.626 x 10^-34 J s)(3 x 10⁸ m/s)/(1.097 x 10⁷ m^-1)(1/1² - 1/4²) = 1.23 x 10⁵ J/molTherefore, the energy of the radiation required to excite an atom from the n₁=1 orbit to the n₂=4 orbit is 1230 kJ/mol of photon.
