**Combustion of Octane Problem**

**Problem Statement**:
Using the following equation for the combustion of octane, calculate the heat associated with the formation of 100.0 g of carbon dioxide. The molar mass of octane is 114.23 g/mol. The molar mass of carbon dioxide is 44.0095 g/mol.

**Chemical Equation**:
\[2 \text{C}_8\text{H}_{18} + 25 \text{O}_2 \rightarrow 16 \text{CO}_2 + 18 \text{H}_2\text{O}\]
\[\Delta H_{rxn} = -11018 \text{ kJ}\]

**Options**:
A) -11018 kJ  
B) -12520 kJ  
C) -1001 kJ  
D) -1565 kJ  
E) -1391 kJ  

**Explanation**:
This problem involves calculating the enthalpy change associated with the production of a specified amount of carbon dioxide from the combustion of octane. Use stoichiometry and the given molar masses to find the correct answer choice.
