Answer:
The pH to be 10 cm from the most acidic end is 3.42.
Explanation:
The pH at one end = 1
The pH at another end = 13
Length of the chamber = 13 cm
Change in pH with respect to length of the chamber from acidic end =
So, the pH of the chamber 10 cm from the most acidic end:
The pH to be 10 cm from the most acidic end is 3.42.

Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.
