Consider the reactions
a) `6CO_(2)(g)+6H_(2)O(I)toC_(6)H_(12)O_(6)(aq)+6O_(2)(g)`
b) `O_(3)(g)+H_(2)O_(2)(I)toH_(2)O(I)+2O_(2)(g)`
Why it is more appropriate to write these reaction as
a) `6CO_(2)(g)+12H_(2)O(I)toC_(6)H_(12)O_(6)+6H_(2)O(I)+6O_(2)(g)`
b) `O_(3)(g)+H_(2)O_(2)(I)toH_(2)O(I)+O_(2)(g)+O_(2)(g)`
Also suggest a technique to investigate the path of the above (a) and (b) redox reactions.

Explanation

(a) 6 `CO_(2)`+12`H_(2)O`to C_(6)H_(12)O_(6)+6`H_(2)O`+6`O_(2)`
This equation is more appropriate writing equation of photosynthesis. Because of evolution of oxygen from `H_(2)O` but not from `CO_(2)`
(b) `O_(3(g))+H_(2)O_(2(l))to H_(2)O_((l))+O_(2(g))+O_(2(g))`
This is the more appropriate equation to write because in this reaction clearly mentioned that which is oxidised and which is reduced.
