For the combustion reaction at `298K`
`2Ag(s)+1//2O_(2)(g) rarr Ag_(2)O(s)`
Which of the following alternatives is correct?

Options

A. `DeltaH = DeltaU`
B. `DeltaH gt DeltaU`
C. `DeltaH lt DeltaU`
D. `DeltaH` and `DeltaU` bear no relation with each other

Explanation

To solve the question regarding the combustion reaction of silver oxide at 298 K, we will analyze the enthalpy change for the reaction:

**Given Reaction:**
\[ 2 \text{Ag(s)} + \frac{1}{2} \text{O}_2(g) \rightarrow \text{Ag}_2\text{O(s)} \]

### Step 1: Understand the Reaction
The reaction involves the formation of silver oxide (Ag₂O) from its elements, silver (Ag) and oxygen (O₂). This is a formation reaction.
