Question

c. Ecell = K
57. Electrochemical cell potentials can be used to determine equilibrium constants that would be otherwise difficult to
determine because concentrations are small. What is K for the following balanced reaction, if E = +0.0218 V?
3Zn(s) + 2Cr+(aq) - → 3Zn+2(aq) + Cr(s)
E = +0.0218 V
a. 1.3 x 10-3
b. 2.2
c. 162
d. 0.37​
