DELTA H AND DELTA E

Identify the reaction for which Delta H != Delta E

For which change Delta H ne Delta E :-

For which of the following change Delta H ne Delta E ?

Under which of the following conditions is the relation, Delta H = Delta E + P Delta V valid for a system :-

1 mole of ice at 0^(@)C and 4.6 mm Hg pressure is converted to water vapour at a constant temperature and pressure. Find Delta H and Delta E if the latent heat of fusion of ice is 80 cal//g and latent heat of vaporisation of liquid water at 0^(@)C is 596 cal//g and the volume of ice in comparison to that of water (vapour) in neglected.

There is 1 mol liquid (molar volume 100 ml ) in an adiabatic container initial, pressure being 1 bar Now the pressure is steeply increased to 100 bar, and the volume decreased by 1 ml under constant pressure of 100 bar. Calculate Delta H and Delta E . [Given 1 "bar"=10^(5)N//m^(2) ]
