Entropy Change for a Reaction

CHEM-YS6D@I

The change in entropy for the following reaction

$$N_{2} + 3H_{2} \rightarrow 2NH_{3}$$

is $-198.1 \ J/mol K$.

If the standard molar entropies of $N_{2}$ and $H_{2}$ are $191.6 J/mol K$ and $130.5 J/mol K$ respectively, what is the standard molar entropy of ammonia?

A

$-979.3 \ J/mol K$

B

$385 \ J/mol K$

C

$192.5 \ J/mol K$

D

$124 \ J/mol K$
