Answer to Question #55759 in General Chemistry for Aleshia

Question

1. The photoelectric effect is the ejection of electrons by a metal when struck with light of
sufficient energy. If a beam of light with energy = 3.960 eV is applied to a sodium metal
surface (work function  = 2.384 eV), what is the maximum kinetic energy of the ejected
electrons? * Ke max; the maximum kinetic energy of the ejected electron

Answer 1

K_E,max = hv - φ = 3.960 eV - 2.384 eV = 1.576 eV
Answer: 1.576 eV
