Question

Answer number 7 please; calculate reaction quotient.

Standard potential Write the cell diagram for the reaction with the cathode on the right side and the cell notation for the cell below it. Calculate the reaction quotient, Q, for the following cell reaction, given the measured value of the cell potential. Balance the chemical equation by using the smallest whole number coefficients. 1.0 M NiSO 4 (og) solution was electroly by using Write the cathode reaction. Write the reaction. What is the minimum potential that must be applied to the cal for the onset of electrolysis

Explanation / Answer

Pb+4 + Sn+2 ----> Pb+2 + Sn+4

Eo = Eo Pb+4/Pb+2 - Eo Sn+4/Sn+2

Eo = 1.69 - 0.15

Eo = 1.54

E= Eo - (0.0591 /n ) log Q

here n=2

1.33 = 1.54 - ( 0.0591/2) log Q

Q = 12782005.05

Q= 1.278 x 10^7
