What is the value for δsºreaction for the following reaction, given the standard entropy values?
al2o3(s) + 3h2(g) → 2al(s) + 3h2o(g)
substance sº(j/mol*k)
al2o3(s) 51
h2(g) 131
al(s) 28
h2o(g) 189
Answers: 2
of the reaction is 
![\Delta S_{rxn}=\sum [n\times \Delta S^o_{products}]-\sum [n\times \Delta S^o_{reactants}]](/tpl/images/0354/1276/ec939.png)
![\Delta S^o_{rxn}=[(2\times \Delta S^o_{H_2O})+(3\times \Delta S^o_{H_2O})]-[(1\times \Delta S^o_{Al_2O_3})+(3\times \Delta S^o_{H_2})]](/tpl/images/0354/1276/e83b3.png)
![\Delta S^o=[(2\times 28)+(3\times 189)]-[(1\times 51)+(3\times 131)]=179Jmol^{-1}K^{-1}](/tpl/images/0354/1276/23814.png)
