For the reaction,
`2CI(g)rarrCI_(2)(g),` what are the signs of `DeltaH and DeltaS` ?

Text Solution

Verified by Experts

The given reaction represents the formation of bonds. Hence, energy is released, i.e., `DeltaH` is -ve. Further, `2 mol` of atoms have greater randomness than `1` mole of molecules. Hence, randomness decreases, i.e., `DeltaS` is -ve.
