The dissociation energy of H2 is 429.0 kJ/mol. If H2 is dissociated by illumination with radiationof wavelength 270.00 nm, then what percentage of radiant energy will be converted into kineticenergy?

Radiations of frequency, (v) are incident on a photosensitive metal. The maximum kineticenergy of photoelectrons is E. When the frequency of the incident radiations is doubled, then whatis the maximum kinetic energy of the photoelectrons?

The intensity of solar radiation reaching the Earth is 1,340 W/m2 when the temperature of the Sun is 5,800 K. If the temperature of the Sun decreased by 10.0%, then what would be the intensity of solar radiation reaching the Earth

10.0 grams of octane are burned in a bomb calorimeter containing 2.00 × 102 g H2O. If the water temperature increases from 25.00°C to 37.00°C, how much energy was released by the system? [SHw = 1.00 cal/(g•°C)]

O2 undergoes photochemical dissociation into one normal oxygen atom and one oxygen atom,1.2 eV more energetic than normal. The dissociation of O2 into two normal atoms of oxygenrequires 482.5 kJ/mol. The maximum wavelength effective for photochemical dissociation of O2 is

The kinetic energy of emitted electron is E when the light incident on the metal has wavelength  λ.To double the kinetic energy, the incident light must have wavelength:
