For `Pt,Cl_(2)(p_(1))|HCl(0.1M)|Cl_(2)(p_(2)), Pt,` cell reaction will be spontaneous if

A

`p_(1)=p_(2)`

B

`p_(1)gtp_(2)`

C

`p_(2)gtp_(1)`

D

`P_(1)=P_(2)=1atm`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(cell)=E_(cell)^(0)-(0.591)/(2)log_(10)((P_(Cl_(2)_(anode)))/(P_(Cl_(2)(cathode))))=0-(0.0591)/(2)log_(10)((P_(1))/(P_(2)))`
if `P_(1)ltP_(2),E_(cell)=+ve` (spontaneous)

Consider the cell : Pt|H_(2)(p_(1)atm)|H^(o+)(x_(1)M) || H^(o+)(x_(2)M)|H_(2)(p_(2)atm)Pt . The cell reaction be spontaneous if

For the following cell with gas electrodes at p_(1) and p_(2) as shown: underset(at P1)(PtCl_(2))underset(1M)(abs(HCl)) underset(at P2)(Pt (Cl_(2)) cell reaction is spontaneous if :

Pt|underset((p_(1)))(H_(2))|underset((1M))(H^(+))||underset((1M))(H^(+))|underset((p_(2)))(H_(2))|Pt (where p_(1) and p_(2) are pressure) cell reaction cell reaction will be spontaneous if:

Galvanic cells generate electrical energy at the expense of a spontaneous redox reaction. In an electrode concentration cell two like electrodes having different concentrations, either because they are gas electrodes operating at different pressures or because they are amalgams (solutions in mercury) with different concentrations are dipped into the same solution. Eg. An example is a cell composed of two chlorine electrodes with different pressure of Cl_(2) : Pt_(L)|Cl_(2)(P_(L))|HCl(aq)|Cl_(2)(P_(R))|Pt_(R) Where P_(L) and P_(R) are the Cl_(2) pressure at the left and right electrodes. Calculate the EMF of the electrode concentration cell represented by : Hg-Zn(c_(1))|Zn^(+2)(aq)|Hg-Zn(c_(2)) At 25^(@)C.c_(1)=2g of Zn per 100g of Hg and c_(2)=1g of Zn per 50g of Hg

STATEMENT-1: The concentration cell underset(P_(1))(PtH_(2)) |HCl| H_(2)Pt, P_(2) would show spontaneous flow of current only when P_1 gt P_2 whereas the concentration cell PtH_(2)|HCl, C_(1)|HCl, C_(2)|H_(2)Pt show spontaneous flow of current only when C_(2) gt C_(1) and STATEMENT-2 Case I: E_("cell")=(0.059)/(2) log""(P_(2))/P_(1)," Case II"E_("cell")=(0.059)/(1) log""C_(1)/C_(2)

The EMF of a galvanic cell Pt|H_(2)(1 atm)|HCl(1M)|Cl_(2)(g)|Pt is 1.29V . Calculate the partial pressure of Cl_(2)(g) . E^(c-)._(Cl_(2)|Cl^(c-))=1.36V .
