table is 18.1 is given. please show work so i understand
4. (a) Use the standard reduction potentials at 25° C in Table 18.1 in Tro, Fridgen and Shaw, and calculate the standard emf E' of an electrochemical cell described by the following reaction: 2 K+ + Mn → Mn + 2 K (b) What is n? (c) What is AGº for this reaction at 25°? (d) What is the equilibrium constant for this reaction at 25°? E (V) Weaker...
Please double check my answers? If they're wrong can you explain how to do it right? My math book doesn't have examples for all of these scenarios and I really don't want to fail this assignment. I don't normally look for help online, but I'm kinda desperate. When I couldn't find a symbol for the exponent I used the ^ 1. 18r⁴ s⁵ t⁶ ÷ -3r² s t³ = ? A. 6r²s⁵t³ B. -6r²s⁵t³ C. 6r²s⁴t³ D. -6r²s⁴t³ 2. One...
