Question

Consider the reactions:
Why it is more appropriate to write these reactions as: $6 C O_{2} (g) + 12 H_{2} O (l) \to C_{6} H_{12} O_{6} (a q) + 6 O_{2} (g) + 6 H_{2} O (l)$
Also suggest a technique to investigate the path of the above (a) and (b) redox reactions.
$6 C O_{2} (g) + 6 H_{2} O (l) \to C_{6} H_{12} O_{6} (a q) + 6 O_{2} (g)$

Solution

The given reaction is
$6 C O_{2} (g) + 6 H_{2} O (l) \to C_{6} H_{12} O_{6} (a q) + 6 O_{2} (g)$
It is more appropriate to write this reaction as
$6 C O_{2} (g) + 12 H_{2} O (l) \to C_{6} H_{12} O_{6} (a q) + 6 O_{2} (g) + 6 H_{2} O (l)$
This is because water is produced during photosynthesis and water must be shown on product side. To investigate the path, $H_{2} O^{18}$ is used instead of $H_{2} O^{16}$ . Thus, instead of using normal O atom in water molecule, we use radioactively labelled O atom in water molecule. By determining the intermediates and products containing labelled oxygen, we can investigate above paths.
