A.) Spontaneous reaction can be dtermined by calculating delta G ( Go)
Go= G products - Greactants = 2(-204.9 ) - ( -394.4) + (-62.3) = -409.8 - (-456.7) = 46.9 kJ/mol
The reaction is non spontaneous because delta G is postive
B.) ln Keq = - Go/ RT = -46.9 kJ/mol / (0.008314kJmol^-1 K^-1 ) * ( 373K) = -15.12
ln Keq = -15.12
Keq = 2.713 x 10^-7
Ho = H products - Hreactants = 2(-219.9) - (-95.7) + (-393.5) = - 439.8 -(-489.2) =49.4 kJ/mol
C.) G = H - TS
G= 0
T = H / S = 49.4/46.9 kJ/mol = 1.05 oC
