Q. For which of the process, $\mathrm{\Delta}S$ is negative?
A) $H_{2}(g) \rightarrow 2H(g)$
B) $2SO_{3}(g) \rightarrow 2SO_{2}(g) + O_{2}(g)$
C) $N_{2}(1\ g\ atom) \rightarrow N_{2}(8\ g\ atom)$
D) $C_{(diamond)} \rightarrow C_{(graphite)}$
Explanation
(c)
When gas is compressed its entropy decreases so, $\mathrm{\Delta}S$ is negative
