Photosynthesis produces glucose, C6H1206, and oxygen from
Chapter 6, Problem 81P(choose chapter or problem)
Photosynthesis produces glucose, \(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\), and oxygen from carbon dioxide and water:
\(6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+6 \mathrm{O}_{2}\)
(a) How would you determine experimentally the \(\Delta H_{r x n}^{\circ}\) value for this reaction? (b) Solar radiation produces about \(7.0 \times 10^{14}\ \mathrm{kg}\) glucose a year on Earth. What is the corresponding \(\Delta H^{\circ}\) change?

ANSWER:Step 1 of 4
(a)
For the given reaction, we can not calculate the for the given reaction. But if we reverse the reaction, we can easily calculate the
of the reaction.
The reverse reaction is
