Question
For a particular reversible reaction at temperature T, ᐃH and ᐃS were found to be both +ve. If Te is the temperature at equilibrium, the reaction would be spontaneous when
Options
A.Te > T
B.T > Te
C. Te is 5 times T
D. T = Te
Solution
ᐃ G = ᐃH - TᐃS
at equilibrium, ᐃG = 0
for a reaction to be spontaneous ᐃG should be negative
∴ T > Te
at equilibrium, ᐃG = 0
for a reaction to be spontaneous ᐃG should be negative
∴ T > Te
