The Change in Standard Molar Entropy $\Delta$ S ^$\circ$ for the Reaction 2 KClO₃(s)

question 102

Short Answer

The change in standard molar entropy, $\Delta$ S ^$\circ$ for the reaction 2 KClO₃(s) $\leftrightarrows$ 2 KCl(s)+ 3 O₂(g)is 494.0 J/mol . K at 25.00 ^$\circ$ C.What is the standard molar entropy of O₂(g)at 25.00 ^$\circ$ C?
S ^$\circ$ (KClO₃,s)= 143.1 J/mol · K
S ^$\circ$ (KCl,s)= 82.6 J/mol · K
