In which case will the equilibrium constant (K) be less than 1 at 298 K?
(a) DeltaH = 4.55 kJ/mol ,deltaS = 28.0 J/mol K
(b) delta H = - 4.55 kJ/mol ,deltaS = 28.0 J/mol K
(c)deltaH = 4.55 kJ/mol ,deltaS= - 28.0 J/mol K
(d) both (a) and (b)
I know the answer is c but I don't know how to approach it.
dG = dH - TdS
Substitute and solve for dG.
Then dG = -RTlnK
Substitute and solve for K.
