Question

The following values may be useful when solving this tutorial. In the activity, dick on the E degree cell and Keq quantities to observe how they are related. Use this relation to calculate Keq for the following redox reaction that occurs in an electrochemical cell having two electrodes: a cathode and an anode. The two half-reactions that occur in the cell are The net reaction is Use the given standard reduction potentials in your calculation as appropriate. Express your answer numerically to three significant figures. In the activity, dick on the Keq and delta G degree quantities to observe how they are related. Calculate delta G degree using this relationship and the equilibrium constant (Keq) obtained in Part A at T = 298 K: Keq = 1.24 times 1020 Express the Gibbs free energy ( delta G degree ) in joules to three significant figures.

Explanation / Answer

we know that

dG = -RT lnKeq

so

dG = -8.314 x 298 x ln 1.24 *10^20

dG = - 114629.36 J

so dG value is -1.15 x 10^5 J

the answer is -1.15 x 10^5 J
