Question
Using the data in the preceding problem, calculate the equilibrium constant of the reaction at 25oC.
Zn + Cu++ ⇋ Zn++ + Cu, K =
Zn + Cu++ ⇋ Zn++ + Cu, K =
Options
A.8.314 × 1024
B.4.831 × 1031
C.8.314 × 1036
D.4.831 × 1044
Solution
E•298 = 1.1028 - 0.641 × 10-3 × 25 + 0.72 × 10-5 × (25)2 = 1.091275 Volt
= - 8.314 × 298 ln K = - 2 × 1.091275 × 96500
K = 1036.91= 8.128 × 1036.
= - 8.314 × 298 ln K = - 2 × 1.091275 × 96500
K = 1036.91= 8.128 × 1036.
