Consider the following redox reaction:
`2lrCl_(6)^(3-)+3HCOOHto2lr+3CO_(2)+12Cl^(-)+6H^(+)`
Given: `CO_(2)+2H_(3)O^(+)+2etoHCOOH+2H_(2)O" "E^(@)=-0.20V`
`lrCl_(6)^(3-)+3etolr+6Cl^(-)" "E^(@)=0.77V`
(a). Determine standard state emf of cell.
(b). Is this reaction thermodynamically spontaneous as written? Briefly explain.
