Assume each reaction is carried out in an open container. For which reaction will $$\Delta $$H = $$\Delta $$E ?

Identify the correct statement for change of Gibb's energy for a system ($$\Delta $$G_system) at constant temperature and pressure.

The enthalpy of hydrogenation of cyclohexene is is $$-$$ 119.5 kJ mol^$$-$$1. If resonance energy of benzene is $$-$$ 150.4 kJ mol^$$-$$1, its enthalpy of hydrogenation would be

The enthalpy and entropy change for the reaction:
Br_2(l) + Cl_2(g) $$ \to $$ 2BrCl_(g)
are 30 kJ mol^$$-$$1 and 105 J K^$$-$$1 mol^$$-$$1 respectively.
The temperature at which the reaction will be in equilibrium is
