dGo = dH - TdS
Subwstitute T, dS, and dH and solve for dG. Then dG = -RTlnK
Solve for K.
Don't forget that dH has units of kJ/mol and dS has units of J/mol.
Nitrosyl chloride (NOCl) decomposes at high temperature. The equation is
2 NOCl (g) -> 2 NO (g) + Cl2 (g) at 227C
Using delta H = 81.2 kJ and delta S = 128 J/K, calculate the value of the equilibrium constant for this reaction.
a 1.60 X 10-2
b. 2.1 X 10-7
c. 62.8
d. 4.9 X 106
e. 3,20 X 109
help no idea?

the new delta s= .128
81.2-(227x.128)=52.144
52.144=-rtlnk
what is rt?

R is 0.08206 just like in PV = nRT.
T is listed in the problem as 227 C (which must be converted to kelvin).
