Question

The combustion of carbon monoxide is exothermic. CO2 (g) + 1/2O2 (g) is equals to CO2(g)                                                 delta H= -283 KJ Determine the delta H of each of the followingreactions. a) 2 CO (g) + O2 (g) is equaled to 2CO2 b) 2CO2 (g) is equaled to 2 CO (g) + O2 (g) The combustion of carbon monoxide is exothermic. CO2 (g) + 1/2O2 (g) is equals to CO2(g)                                                 delta H= -283 KJ Determine the delta H of each of the followingreactions. a) 2 CO (g) + O2 (g) is equaled to 2CO2 b) 2CO2 (g) is equaled to 2 CO (g) + O2 (g)

Explanation / Answer

I think a mass balance is in order for these rxn's, both willhave the same number but different signs. The originalequation is 1/2 of the other two so, 2*H=566KJ; since a) proceedsin the same way as the original a)-566kJ and b)566kJ.
