Question 12 Given the reaction: Cu + Ag+ - Cu+ + Ag The reacxtion is is assumed to be that (Cul+)=(Ag1+)=1.0M and T = 298 K. As the reaction proceeds, Cu1+=0.2 M while Ag1+=1.80M. This occur after one minute. What is EMF of the cell? normal expression What is the E of the cell after one minute? normal expression What is the Keg for this reaction? (Express in scie ^+3 entific notation, in this manner, ex. 1.25x10 All answers in 2 decimal places.
