Photosynthesis produces glucose, c6h12o6, and oxygen from carbon dioxide and water: 6co2(g) + 6h2o(l) → c6h12o6(s) + 6o2(g) co2(g)δh o f = −393.5 kj/mol h2o(l)δh o f = −285.8 kj/mol c6h12o6(s)δh o f = −1274.5 kj/mol assume solar radiation produces about 7.12 × 1014 kg of glucose a year on earth. what is the corresponding δh o change?
