If the energy absorbed per mole of photons is 450 kJ, the number of Einsteins absorbed per 1 mole.

When propionic aldehyde in vapor form at 200 mmHg and 30°C is irradiated with radiation of wavelength 302 nm, the quantum yield with respect to the formation of CO is 0.54. If the intensity of the incident radiation is 1.5x10-3 W, find the rate of formation of CO.

Does Avogadro's number have units?

Explain why the total E in an Einstein depends on the frequency or wavelength of the light.

If the dissociation energy of one mole of O2 is 5.17 eV, determine the wavelength that must be used to dissociate it with electromagnetic radiation. Indicate how many Einstein's of this radiation are needed to dissociate 1 liter of O2 at 25°C and 1 atm of pressure.Data: 1 eV = 96485 kJ mol-1; R = 0.082 atm L K-1; c = 2.998x108 m s-1; h = 6.626x10-34 J s; NA = 6.022x 1023 mol-1

Indicate the number of Einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy (wavelength 475 nm).

Indicate the number of einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy?

A unit used in photochemistry is the einstein. If 400 kJ mol-1 of energy has been absorbed, how many einsteins is this equivalent to?
