A) \[{{H}_{2}}(g)\to 2H(g)\]
B) \[{{N}_{2}}(g)\,1atm\to {{N}_{2}}(g)\,8\,atm\]
C) \[2S{{O}_{3}}(g)\to 2S{{O}_{2}}(g)+{{O}_{2}}(g)\]
D) \[{{C}_{(diamond)}}\to {{C}_{(graphite)}}\]
Correct Answer: B
Solution :
Processes A and C take place with the increase of no. of moles of gaseous species and hence the disorder or entropy increases. B on increasing pressure, disorder or randomness decreases and so also the entropy D is endothermic process and \[\Delta S\]is positive.
