Question

N=8, E=-0.04(e not) E=0.412V(just e) T=298.15KK.Calculate pQ.

Answer 1

nernst

E = Eo - (0.0592/n) (log Q)

0.412 = - 0.04  - (0.0592/8) (log Q)

0.452 =  - (0.0074) (log Q)

(log Q) = -61.08

pQ = - log Q = + 61.08

Your answer is : pQ = + 61.1

I am going to leave the significant digits up to you, unless "Eo=-0.04" had more more zeroes, it became a 2 sigfig problem when 0.04 was added to 0.412 volts

why such a large pQ, because that is a tremendous difference from Eo to E
