For which one of the follwing reactions does not molar enthalpy change of a reaction corresponds to the lattice enegry of `KBr`.

Options

A. `K(s) +1//2Br_(2)(l) rarr KBr(s)`
B. `K(g) +1//2Br_(2) rarr KBr(s)`
C. `K(g) +Br(g) rarr KBr(g)`
D. `K^(Theta)(g)+Br^(Theta)(g)rarr KBr(s)`

Explanation

To determine which reaction does not correspond to the molar enthalpy change related to the lattice energy of KBr, we must first understand what lattice energy is and how it relates to enthalpy changes in reactions involving ionic compounds.

### Step-by-Step Solution:

1. **Understanding Lattice Energy**:
Lattice energy is the energy released when gaseous ions combine to form an ionic solid. It can also be viewed as the energy required to separate one mole of a solid ionic compound into its gaseous ions.

2. **Identifying the Reactions**:
