The thermodynamic property that measures...

The thermodynamic property that measures the extent of molecular disorder is called entropy. Entropy change of phase transformation can be calculated using Trouton's formula `(DeltaS = DeltaH//T)`. In the reversible adiabatic process, however, `DeltaS` will be zero. the rise in temperature in isobaric and isochoric conditions is found to increase the randomness or entropy of the system.
`DeltaS = 2.303 C log (T_(1)//T_(2))`

A

Zero

B

Positive

C

Negative

D

Remains same

Text Solution

Verified by Experts
