$4B(s) + 3O_2\,(g) \rightarrow 2B_2O_3\,(g)$ ; $E^o_{cell} = 1.433$ $volt$ What is molar entropy (in $J/K$) of oxygen gas
Given ${\left( {{\Delta _f}{H^o}} \right)_{{B_2}{O_3}}}\left( g \right) = - 840\,\frac{{KJ}}{{mol}}$
${\left( {S_m^o} \right)_{{B_2}{O_3}}} \left( g \right) = 280J/K - mol$
${{(S_{m}^{o})}_{B}}\,\,\left( s \right)=10\,J/K-mol$
