IIT JAMChemistryChemical ThermodynamicsNumerical+1 / −0
Consider the reaction CO(g)+12O2(g)⟶CO2(g)CO(g) + \frac{1}{2} O_2(g) \longrightarrow CO_2(g)CO(g)+21​O2​(g)⟶CO2​(g). The value of ΔU\Delta UΔU for the reaction at 300 K is -281.8 kJ mol −1^{-1}−1. The value of ΔH\Delta HΔH at same temperature is kJ mol −1^{-1}−1 (rounded up to the first decimal place). [R=8.3 J K−1 mol−1][R = 8.3 \text{ J K}^{-1} \text{ mol}^{-1}][R=8.3 J K−1 mol−1]
