Calculating delta G question? plz help and explain thnx much?

Question

consider the reaction A<--->B + C, where the standard delta G=0.00

calculate the value of delta G when the initial concentrations of A, B, and C are each 1 M, 10^-3 M and 10^-6M at 25 degreCelsiusus

Answer 1

We know that...

ΔG = ΔG° + RTlnQ

R = 8.314 J/ K*mol

T = temperature in Kelvins = assume 298K

Q = equilibrium quotient. Solve for Q using the concentrations and your balanced equation.

Solve for Qc = [products]/[reactants]

T = 298

R = given above

ΔG = 0

Plug and chug.
