For the cell Pt||H_2(0.4atm)|H^+(pH=1)||(H^+(pH=2)|H_2(0.1atm)|Pt The measured potential at 25^(@)C is

Redox reactions play a pivotal role in chemistry and biology. The values of standard redox potential (E^(@)) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited. For the cell: Pt |H_(2)(0.4"atm")H^(+)(pH=1)||H^(+)(pH=2)|H_(2)(0.1"atm")| Pt, the measured potential at 25^(@)C is: [Given: 2.303RT/F=0.06V, log 2=0.3]

For the cell Pt_((s)), H_(2) (1 atm)|H^(+) (pH=2)||H^(+) (pH=3)|H_(2) (1atm),Pt The cell reaction is

Pt(H_(2))(1atm)|H_(2)O , electrode potential at 298K is

At 25^(@)C, DeltaH_(f)(H_(2)O,l) =- 56700 J//mol and energy of ionization of H_(2)O(l) = 19050J//mol . What will be the reversible EMF at 25^(@)C of the cell, Pt|H_(2)(g) (1atm) |H^(+) || OH^(-) |O_(2)(g) (1atm)|Pt , if at 26^(@)C the emf increase by 0.001158V .

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

The cell Pt|H_(2)(g,01 bar) |H^(+)(aq),pH=x||Cl^(-)(1M)|Hg_(2)Cl_(2)|Hg|Pt has emf of 0.5755 V at 25^(@)C the SOP of calomel electrode is -0.28V then pH of the solution will be

The observed emf of the cell, Pt|H_(2) ("1 atm")|H^(+)(3xx10^(-4) M)||H^(+) (M_(1))|H_(2) ("1 atm")|Pt is 0.154 V. Calculate the value of M_(1) and pH of cathodic solution.
