Question
Assertion: `"E"_("Ag"^+ //"Ag")` increases with increase in concentration of Ag+ ions.
Reason: `"E"_("Ag"^+ //"Ag")` has a positive value.
Options
Both assertion and reason are true and the reason is the correct explanation of assertion.
Both assertion and reason are true and the reason is not the correct explanation of assertion.
Assertion is true but the reason is false.
Both assertion and reason are false.
Assertion is false but reason is true.
Solution
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.

The following questions are case-based questions. Read the passage carefully and answer the questions that follow:
| Rahul set up an experiment to find the resistance of aqueous KCl solution for different concentrations at 298 K using a conductivity cell connected to a Wheatstone bridge. He fed the Wheatstone bridge with a.c. power in the audio frequency range 550 to 5000 cycles per second. Once the resistance was calculated from the null point, he also calculated the conductivity K and molar conductivity ∧m and recorded his readings in tabular form. |
