The heat enegry required to ionise the following molecules is given as follows:
`N_(2)(g) overset(DeltaH_(1))rarr N_(2)^(o+(g),O_(2)(g) overset(DeltaH_(2))rarrO_(2)^(o+(g)`
`Li_(2)(g) overset(DeltaH_(3))rarrLi_(2)^(o+(g),C_(2)(g) overset(DeltaH_(4))rarrC_(2)^(o+(g)`
Arrange the heat terms in decreasing order of enegry:

Options

A. `DeltaH_(1) gt DeltaH_(3) gt DeltaH_(2) gt DeltaH_(4)`
B. `DeltaH_(2) gt DeltaH_(3) gt DeltaH_(1) gt DeltaH_(4)`
C. `DeltaH_(3) gt DeltaH_(4) gt DeltaH_(1) gt DeltaH_(2)`
D. `DeltaH_(3) gt DeltaH_(1) gt DeltaH_(4) gt DeltaH_(2)`

Explanation

To solve the problem of arranging the heat energy required to ionize the given molecules in decreasing order, we can follow these steps:

### Step 1: Understand the Ionization Energy Concept
Ionization energy is the energy required to remove an electron from a gaseous atom or molecule. Generally, smaller molecules or atoms have higher ionization energies due to their stronger attraction between the nucleus and the electrons.

### Step 2: Analyze the Given Molecules
The molecules given are:
- \( N_2 \)
