Please only use the numbers and equations in this problem. I will give anyone who gives me a good worked out problem with the numbers provided and answers that aren't pasted from another question a full star rating. I really apprecited your time! I am having a tough time with this! ITS DUE AT MIDNIGHT!
Calculate the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is 0.0004 molar and everything else is standard (use 298 K for the temperature, R = 8.314 J/mol-K, and F = 96,485 C/mol)
