1.	Which is a good fuelCH_(4) orC_(2)H_(6) ? The standard enthalpy of formation of CH_(4), C_(2)H_(6), CO_(2) and H_(2)O are - 74.8, - 84.6 , - 393 . 5 and -286kJ mol^(-1) respectively.
Answer» SOLUTION :Calculate `Delta H `for `CH_(4) + 2O_(2)RARR CO_(2)+ 2H_(2)O` and `C_(2)H_(6) + (7)/(2) O_(2) rarr 2CO_(2)+ 3H_(2)O` Then calculate `Delta H ` per gram
