Discuss the relationship between `DeltaU, DeltaH , q_p` and w for the dissociation of ammonia carried out under constant pressure.
`2NH_3(g) overset("heat") to N_2(g) + 3H_2(g)`

Explanation

To discuss the relationship between ΔU (change in internal energy), ΔH (change in enthalpy), q_p (heat at constant pressure), and w (work done) for the dissociation of ammonia under constant pressure, we can follow these steps:

### Step 1: Write the Reaction
The dissociation of ammonia can be represented as:
\[ 2NH_3(g) \overset{\text{heat}}{\rightarrow} N_2(g) + 3H_2(g) \]

### Step 2: Understand the First Law of Thermodynamics
The first law of thermodynamics states:
