Smiling Face with Glasses Have you learned about this formula? -- deltaG*' = -RTlnKeq

What is the delta G (dG) for a reaction with an equilibrium constant of 10 at 25C ?
R=8.3145 J/(mol*K)
Give the answer in kJ

where R is the gas constant 8.314 J/(mol*k)
T is in Kelvins so 25C +273= 298K
Keq = 10

Use the formula above to obtain delta G.
Note: there is a difference with obtaining free delta G vs delta G *" where *=knot "=prime.
delta G = delta H- Tdelta S...but here use delta G*"= -RTlnKeq
Ask another question, I may be able to help!
