Question Explanation:

Find the entropy of the system.

Concept:

This question is based on entropy calculation.

Solution:

The change in entropy ( $Δ S$ ) can be calculated using the formula:

$Δ S = \frac{Δ H}{T}$

$Δ S = \frac{- 300 \times 1000}{1000}$

$Δ S = - 300 c a l / K$

Final Answer:

The correct option is (B).
