What is ?S° for the reaction: 2 N?(g) + 5 O?(g) --> 2 N?O?(g) ?S° = ? 2 H?(g) + O?(g) --> 2 H?O(l) ?S° = -326.68 J/K N?O?(g) + H?O(l) --> 2 HNO?(l) ?S° = -114.43 J/K 1/2 N?(g) + 3/2 O?(g) + 1/2 H?(g) --> HNO?(l) ?S° = -313.26 J/K -697.5 J/K -754.37 J/K -811.93 J/K -1350.86 J/K

          What is ?S° for the reaction: 2 N?(g) + 5 O?(g) --> 2 N?O?(g) ?S° = ?
2 H?(g) + O?(g) --> 2 H?O(l)  ?S° = -326.68 J/K
N?O?(g) + H?O(l) --> 2 HNO?(l)  ?S° = -114.43 J/K
1/2 N?(g) + 3/2 O?(g) + 1/2 H?(g) --> HNO?(l)  ?S° = -313.26 J/K
-697.5 J/K
-754.37 J/K
-811.93 J/K
-1350.86 J/K

What is ?S° for the reaction: 2 N?(g) + 5 O?(g) –> 2 N?O?(g) ?S° = ?
2 H?(g) + O?(g) –> 2 H?O(l) ?S° = -326.68 J/K
N?O?(g) + H?O(l) –> 2 HNO?(l) ?S° = -114.43 J/K
1/2 N?(g) + 3/2 O?(g) + 1/2 H?(g) –> HNO?(l) ?S° = -313.26 J/K
-697.5 J/K
-754.37 J/K
-811.93 J/K
-1350.86 J/K

Thanks for your feedback!

Please help me find the right answer (-754 is also known to be incorrect) What is so for the reaction:2 N2(g) + 5 O2(g) --> 2 N2O5(g) so=? 2 H2(g) + O2(g) -s> 2 H2O(I) so= -326.68 J/K N2O5(g) + H2O(I) -->2 HNO3(I)So= -114.43 J/K 1/2 N2(g) + 3/2 O2(g) + 1/2 H2(g) -->HNO3(I) S=-313.26 J/K -697.5 J/K -754.37 J/K . -811.93 J/K -1350.86 J/K
