For the gaseous reaction involving the complete combustion of isobutane

Options

A. `DeltaH = DeltaU`
B. `DeltaH gt DeltaU`
C. `DeltaH = DeltaU = 0`
D. `DeltaH lt DeltaU`

Explanation

To solve the problem regarding the complete combustion of isobutane (C4H10) and the relationship between ΔH (enthalpy change) and ΔU (internal energy change), we can follow these steps:

### Step 1: Write the balanced chemical equation for the combustion of isobutane.
The complete combustion of isobutane can be represented as follows:

\[ \text{C}_4\text{H}_{10} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]

To balance it, we need to determine the number of moles of each product and reactant:
