Introducing Chemistry
- The quantum yield of the photochemical decay of HI is 2. Calculate the number of Einsteins absorbed per mole knowing that the energy absorbed per mole of photons is 490 kJ.arrow_forwardThe quantum yield of the photochemical decay of HI is 2. How many moles of HI per kJ of radiant energy can be decayed knowing that the energy absorbed per mole of photons is 490 kJ.arrow_forwardIf the energy absorbed per mole of photons is 450 kJ, the number of Einsteins absorbed per 1 mole.arrow_forward
- 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.arrow_forwardDraw mechanismarrow_forwardDoes Avogadro's number have units?arrow_forward
- Explain why the total E in an Einstein depends on the frequency or wavelength of the light.arrow_forwardIf 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-1arrow_forwardIndicate the number of Einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy (wavelength 475 nm).arrow_forward
- Indicate the number of einsteins that are equivalent to 550 kJ mol⁻¹ of absorbed energy?arrow_forwardA unit used in photochemistry is the einstein. If 400 kJ mol-1 of energy has been absorbed, how many einsteins is this equivalent to?arrow_forwardFor the condensation reaction between Alanine and histidine write the amididation reaction mechanism using arrows then write the three letter code for the product of the reaction and the one letter code for the product of the reaction.arrow_forward
