निम्नलिखित `E^@` मानों पर विचार कीजिए
`E(_Fe^(3+)//Fe^(2+))^@ = 0.77V`
`E_(Sn^(2+)//Sn)^@ = -0.14V`
मानक परिस्थितियों में निम्न अभिक्रिया के लिए विभव है-
`Sn("ठोस") +2Fe^(3+) (" जलीय")to 2Fe^(2+) ( "जलीय") + Sn^(2+) ( "जलीय")`

A

1.68 V

B

0.91 V

C

0.63 V

D

1.46 V

Text Solution

Verified by Experts

The correct Answer is:
B
`Sn( "ठोस") + 2Fe^(3+) ( "जलीय") to 2Fe^(2+) ( "जलीय") + Sn^(2+) ( "जलीय")
`E_("सेल")^@ = (E_("अपचयन")^@ )_("कैथोड") -(E_("अपचयन")^@)_("एनोड")`
`E_("सेल")^@ = 0.77-(-0.14)`
`:. E_("सेल")^@= -0.91V`
