(a)
Interpretation:
The balance coupled chemical equation for the coupled reaction of 1,3-bisphosphoglycerate with ADP to form 3-phosphoglycerate and ATP with the help of given reaction equations needs to be determined.
Concept Introduction:
Born- Haber cycle is used to compute the lattice energy of ionic compounds. Lattice energy can be defined as the energy that is needed to break a compound to its constituent's elements. It can also defineas the energy released during the formation of ionic compounds from its constituent elements. It is based on the Hess law. The Hess law states that the enthalpy change for multistep

Answer to Problem 31P
Explanation of Solution
Given:
To get equation for the coupled reaction of 1,3-bisphosphoglycerate with ADP to form 3-phosphoglycerate and ATP, reverse the equation (2) and add it with (1):
Hence the coupled equation must be:
(b)
Interpretation:
The energy change for the balance coupled reaction of 1,3-bisphosphoglycerate with ADP to form 3-phosphoglycerate and ATP with the help of given reaction equations needs to be determined.
Concept Introduction:
Born- Haber cycle is used to compute the lattice energy of ionic compounds. Lattice energy can be defined as the energy that is needed to break a compound to its constituent's elements. It can also define as the energy released during the formation of ionic compounds from its constituent elements. It is based on the Hess law. The Hess law states that the enthalpy change for multistep chemical reaction is the sum of all enthalpy changes. It can be written as;

Answer to Problem 31P
The given reaction can be used for the formation of ATP from ADP.
Explanation of Solution
Given:
Since the energy change for the formation of ATP from ADP is energetically favored because the energy change is negative here therefore it can be used for the formation of ATP from ADP.
