Tollen's reagent is used for the detection of aldehyde when a solution of `AgNO_(3)` is added to glucose with `NH_(4)OH` then gluconic acid is formed
`{:(Ag^(+)+e^(-)rarrAg,,,E_(red)^(@) =0.8V),(C_(6)H_(12)O_(6)+H_(2)OrarrC_(6)H_(12)O_(7)("Gluconic acid")+2H^(+)+2e^(-),,,E_(red)^(@)=-0.05V),(Ag(NH_(3))_(2)^(+)+e^(-)rarrAg(s)+2NH_(3),,,E^(@) =- 0.337V):}`
[Use `2.303 xx (RT)/(F) = 0.0592` and `(F)/(RT) = 38.92` at `298K]`
`2Ag^(+) +C_(6)H_(12)O_(6)+H_(2)O rarr 2Ag(s) +C_(6)H_(12)O_(7)+2H^(+)` Find In K of this solution

Options

A. 66.13
B. 58.38
C. 28.3
D. 46.29

Answer

B

Explanation

`2Ag^(+)+C_(6)H_(12)O_(6)+H_(2)to2Ag(s)+C_(6)H_(12)O_(7)+2H^(+),E^(@)=0.8-0.05=0.75"volt"`
`0=0.75-(0.0592)/92)logK`.
in `K=2.303xxlogK=2.303xx25.34=58.38`
