1.	For the reaction 2Cl(g)rarrCl_(2)(g), the signs of DeltaHand DeltaS respectively are
Answer» `+,-` `+,+` `-,-` `-,+` Solution :Whenatoms combine to form molecule,energy is released,i.e., `DeltaH ` is `-ve`. As TWO moles combine to give ONE mol, randomness ( ENTROPY) DECREASES,i.e., `eltaS` is `-ve`.
