**Problem Statement:**Determine the value of ΔH° for the following reaction: \[ 2 \text{CO}(g) + \text{O}_2(g) \rightarrow 2 \text{CO}_2(g) \]**Data Provided:**| Substance | ΔH°f (kJ/mol) ||-----------|---------------|| CO(g) | -110.5 || CO2(g) | -393.7 |**Options:**a) -283.2 b) -504.2 c) -566.4 d) -1008.4 e) Not enough information provided. **Explanation:**To calculate the standard enthalpy change (ΔH°) for the reaction, use the formula:\[ \Delta H^\circ = \sum \Delta H^\circ_f \text{ (products)} - \sum \Delta H^\circ_f \text{ (reactants)} \]Calculate:\[ \Delta H^\circ = [2 \times (-393.7)] - [2 \times (-110.5)] \]\[ \Delta H^\circ = (-787.4) - (-221.0) \]\[ \Delta H^\circ = -787.4 + 221.0 \]\[ \Delta H^\circ = -566.4 \]Thus, the correct option is c) -566.4.
