Question

At 298 K, ${\Delta }_f{S}^{\ominus }element=0$.

• A. True
• B. False

Answer 1

The correct option is B False

Entropy of every perfectly crystalline substance is zero at zero Kelvin. This is justified because at absolute zero every substance is in the state of lowest energy and position of every atom or molecule is defined in solid.
${\Delta }_f{S}^{\ominus }element=0$ at $0K$.
