In a flask colourless \( \mathrm{N}_{2} \mathrm{O}_{4} \) is in equilibrium with brown coloured \( \mathrm{NO}_{2} \). At equilibrium when the flask is heated at \( 100^{\circ} \mathrm{C} \), the brown colour deepens and on cooling it becomes less coloured. The change in enthalpy, \( \Delta H \) for this system is:
(A) negative
(B) positive
(C) zero
(D) undefined
