Answer to Question #7247 in Physical Chemistry for kyle

Question

O2 molecules can dissociate to form O atoms by absorbing electromagnetic radiation. If it takes 489 kJ to dissociate one mole of O2 molecules to form two moles of O atoms, what is the frequency of the light that would have just enough energy to decompose a single O2 molecules into O atoms?
a) 1.25 x 10^15 s^-1
b) 8.27 x 10^-19s^-1
c) 7.52 x 10^38s^-1
d) 8.0x10^-16s^-1
e) 5.72 x 10^16s^-1
