QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - EXAMPLE 31.3 : In photoelectrical effect analysis of quantum chemistry, let E = kinetic energy of electron, p = intensity of UV light, f = frequency of UV light. According to Classical Theory, E = c for all values of f, E = mp. According to Quantum Theory, E = c for all values of p, E = mf + c. In a graph, m and c are constants where m is slope and c is y intercept. If m = 2 and c = 3 with similar value of E : (a) find the value of p according to Classical Theory; (b) find the value of f according to Quantum Theory.

QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - ANSWER 31.3 : (a) E = c = 3, then E = mp = 2p = 3, then p = 3 / 2. (b) E = c = 3, then E = mf + c = 2f + 3 = 3, then f = (3 - 3) / 2 = 0.
