Using the given data calculate enthalpy of formation of acetone (g). [All value in "KJ mol"^(-1)] bond enthalpy of : {:(C-H=413.4,,,C-C=347.0,,,(C=O)=728.0,,),((O=O)=495.0,,,H-H=435.8,,,Delta_("sub")H" of "C=718.4.,):}

Answer»


Solution :`3C+3H_(2)+1/2 O_(2) rarr CH_(3) -underset(O)underset("||")(C)-CH_(3)`
Calculate `DeltaH`
`DeltaH=-192.3" kJ MOL"^(-1)`
