Question

15. Solar water-splitting is extensively explored as a promising alternative source of renewable energy (Cho, J., et al. Acc. Chem. Res. 2019, 52, 645-655). This fossil fuel-independent technology involves solar light harvesting and the redox reaction of water to produce energy-dense fuels, H2, and O2: H2O(l) → H2(g) + 1/2O2(g); ΔΗrxn = +286 kJ How much heat is evolved when 27.1 g O2 (M = 32.00 g/mol) is produced? a. +121 kJ b. +484 kJ c. +1.52 kJ d. +242 kJ
