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 the change in enthalpy (ΔH) and the change in internal energy (ΔU), we will follow these steps:

### Step 1: Write the balanced chemical equation for the complete combustion of isobutane.

The complete combustion of isobutane can be represented as follows:

\[
\text{C}_4\text{H}_{10(g)} + \text{O}_{2(g)} \rightarrow \text{CO}_{2(g)} + \text{H}_2\text{O}_{(g)} + \text{heat}
