MCQ

उत्तर

Both assertion and reason are true and the reason is not the correct explanation of assertion. 

Explanation:

\[\ce{Ag- + e- -> Ag}\]

`"E"_("Ag"^+//"Ag") = "E"_("Ag"^+//"Ag")^0 - 0.059/1 log  1/(["Ag"^+])`

= `"E"_("Ag"^+//"Ag")^0 + 0.059["Ag"^+]`

On increasing \[\ce{[Ag+], E_{Ag^+/Ag}}\] will increase and it has a positive value.
