(a) Calculate the enthalpy change for the production of one mole of glucose by the process of photosynthesis at 25°C. Δ_fH° [glucose(s)] = −1273.3 kJ/mol

(b) What is the enthalpy change involved in producing one molecule of glucose by this process?
(c) Chlorophyll molecules absorb light of various wavelengths. One wavelength absorbed is 650 nm. Calculate the energy of a photon of light having this wavelength.
(d) Assuming that all of this energy goes toward providing the energy required for the photosynthetic reaction, can the absorption of one photon at 650 nm lead to the production of one molecule of glucose, or must multiple photons be absorbed?
