Blood → Gastric Juice
pH = 7.6021
[H+] = 2.5×10-8
∆G° = -RTlnK
= - RTln [1/2.5×10-8] (since, concentration of gastric juice be taken as unity and we have blood in reactant)
= 47443.26
Now for 1 mole(22.4L) we have Energy = 47443.26
So, for 1dm3(1 L), we have
=47443.26/22.4
=2 kJ
And so according to me, the correct answer is 2 and not 4.

The given information states that the pH of the gastric juice is 7.6021.
To find the value of [H+], we need to find the value of 10-pH.
10-pH = 10^-7.6021
Using a calculator, we find that 10^-7.6021 is approximately 2.616 x 10^-8.
Therefore, the value of [H+] in the gastric juice is approximately 2.616 x 10^-8.
Since we need to find an integer from 0 to 9, we can round this value to the nearest integer, which is 0.
Thus, the answer to this question is 0.
