To calculate the standard enthalpy change H for the combustion reaction of ethanol, we need to know the amount of ethanol combusted. Since we are given the heat evolved 1367.6 kJ and the molar mass of ethanol 46.07 g/mol , we can use these values to find the moles of ethanol combusted and then calculate the standard enthalpy change per mole.First, let's find the moles of ethanol combusted:Heat evolved = 1367.6 kJMolar mass of ethanol = 46.07 g/molHeat of combustion per gram of ethanol = -1367.6 kJ/mol 46.07 g/mol = -29.68 kJ/gNow, we can calculate the standard enthalpy change H for the combustion reaction of ethanol:H = Heat of combustion per gram of ethanol Molar mass of ethanolH = -29.68 kJ/g 46.07 g/molH = -1367.6 kJ/molSo, the standard enthalpy change H for the combustion reaction of ethanol is -1367.6 kJ/mol.
