University of Guelph CHEM 1050 Search Q&A; | Chegg.com (1) CHEM1050 Question 3 of 100 Map this question was wittenby Dan Thomas at University of Guelph sapling learning Calculate the potential delivered by a voltaic cell operating by the following reaction if all of the dissolved species have a concentration of 0.060 and the pressure of H2 (g) is 1.00 atm. The standard cell potential is +0.392 V. Zn(s)+ 2H20 (1)+2 OH (aq)->Zn(OH)4(a) +H2 (g) Number

Explanation / Answer

Ecell = E0 -0.0591/2 logQ

n = 2

concentraction of all species are 0.06M

Ecell = E0 -0.0592/2log[(Zn(OH)4)2-]/[OH-]2

Ecell   = 0.392-0.0591/2log0.06/(0.06)2

          = 0.392-0..02995*1.221

          = 0.392-0.036 = 0.356V >>> answer
