Breaking the oxygen-oxygen bond in hydrogen peroxide requires 210 kJ/mol. What is the longest wavelength of light that can cause this bond to be broken A) 5.7 * 10^-4 m B) 9.5 * 10^-31 m C) 2.8 * 10^-7 m D) 9.5 * 10^-28 m E) 5.7 * 10^-7 m

Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ. Solving for λ gives λ = hc/E. Using h = 6.626 x 10^-34 J·s, c = 3.00 x 10^8 m/s, and E = 210,000 J/mol (converted from kJ), the longest wavelength is approximately 5.7 x 10^-7 m.
