IUcrtify all uf the folbu iry staicmert teal are true reqanting cell pvemtiale. Cell potentials are a measure of the relative tendencies of the reactants to underga reduction. Cell potentials are NOT dependent on temperature. A positive cell patential indicates the reaction is non-spontaneous. Cell potentials depend on concentration af reactants and products in the aqueous and gas phases. Voltaic cells must have positive cell poteritials. Question 2 (0.25 points) When writing cell notation for electrochemical cells, which of the following statements are true? A double vertical line represents a salt bridge The axidation half-reaction is listed first (non the left) and the reduction halfreacticn is on the right. A single vertical line represents the presence of an inert (passive) electrode. Question 3{0.25 points\} Cu24+2e−→Cu(s)Femad​−+0.34 V Sn21+2e−→Sn(x)F′ned​−−0.14 V The cupper halfectl will erve a the ande. Cu24 will be raluecal. Sn (a) will he the rahucing agent. Question 4[0.25 points\}] Using the table of reduction patentiols below, which redoos resction listed can be used to make a valtaic cell with the largest standard cell patentiol. Cr31+3Fe21→3Fe5t+Cr(a) 3Fe20+2Cr→2Cr3t+3Fe 2Fe31+Sn21→Sn41+Fe21 3Sn41​+2Cr→2Cr3t+3Sn2t
