Answer to Question #280823 in Physical Chemistry for Ellyite

Question

The change in enthalpy is 2kjmol-1 when graphite is converted to diamond. Find work and internal energy when 1 mole of graphite is converted to diamond at 1 bar pressure if density of graphite is 2.3 and diamond is 3.3 gcm-1

Answer 1

The enthalpy change when 1 mol of graphite is converted into a diamond is known as the enthalpy of transition.It is equal to 1.9kJΔHtransition​=Hdiamond​−Hgraphite​=1.9kJ.
