निम्नलिखित सेल के लिए, `Zn(s) | Znso_4 (aq) | | CuSO_4, (aq) | Cu (s)` जब `Zn^(2+)` की सांद्रता `Cu^(2+)` की सांद्रता से 10 गुना हो, तब `DeltaG (J mol^(-1)` में) के लिए व्यंजक है: [F फैराडे स्थिरांक है, R गैस स्थिरांक है, T तापमान है, `E^@` (सेल) = 1.1 V]

A

2.303 RT + 1.1 F

B

1.1F

C

2.303 RT - 2.2 F

D

`- 2.2 F`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG=DeltaD^@=2.303RT log _(10)Q,Q =([Zn^(2+)])/([Cu^(2-)])`
`=-2F (1.1) +2.303 RT log_(10)10`
`= 2.303 RT = 2.2 F`
