1)
delta G = - 3.680 KJ/mol = -3680 J/mol
T = 25.0 oC =(25.0+273)K = 298.0 K
use:
delta G = -R*T*ln Kc
-3680.0 = - 8.314*298.0* ln(Kc)
ln Kc = 1.485
Kc = 4.42
Answer: 4.42
2)
T = 37.0 oC =(37.0+273)K = 310.0 K
Q = [B]/[A]
= 0.60/1.8
= 0.333
use:
delta G = + delta Go + R*T*ln Q
= -3680 + 8.314*310*ln (0.333)
= -6514 J/mol
= -6.514 KJ/mol
Answer: -6.514 KJ/mol
