In an experiment of electroplating, 4 ampere electric current is passed for 2 minutes. Hence, m gram Ag is deposited at cathode. If 6 ampere current is passed for 40 second, then what amount Ag is deposited at cathode ?
Which of the following is correct form of the nernst equation to determine the oxidation potential of $Cu/Cu^{2+} $ half cell ?
What amount of electric charge required for the reduction of 1 mole $Cr_2O_7 ^{2– }into Cr^{3+} $ theoretically ?
What does the potential of the electrochemical cell become zero ?
For the electrochemical cell, $ Mg|Mg^{2+ } (0.04m)||Ag^+_{(c_2)} |Ag ; Ecell = E ^\circ cell, then what will be the value of C_2 $ ?
Which of the following possesses maximum equivalent conductance at infinite dilution?
Cs⺠(Cesium ion) has the maximum equivalent conductance at infinite dilution among the given options. This is because larger ions have less hydration and thus move more freely in solution. In this case, Cs⺠is larger than Kâº, Naâº, and Rbâº, making it the ion with the highest equivalent conductance at infinite dilution.
The potential of a cell is 2.0 volt. change in free energy (SG) occur for the reaction of cell is –50k.cal then what coulomb electric charge obtained from the cell?
The change in free energy (ΔG) for a cell reaction is related to the electric charge (Q) and the cell potential (E) by the equation ΔG = -nFE, where n is the number of moles of electrons, F is the Faraday constant (approximately 96485 C/mol), and E is the cell potential. Given ΔG = -50 kcal (which is -50,000 cal) and E = 2V, we can rearrange the equation to find Q: Q = rac{-ΔG}{E} = rac{50000}{2} = 25000 C.
$ A+ 25 ^\circ $ c temperature and 1 bar pressure, oxidation potential of hydrogen half cell is 0.118 volt, then what would be the $ P^{OH} $ of the solution?
For the electrochemical cell, $ Zn|Zn^{2+}_{(C_1)} ||Cu^{2+ } _{C_2} |Cu ; Ecell > E ^\circ $ Cell then., what change occurs in the value of cell potential, when concentration of both the solution decreased equally ?
Which equation is suitable to calculate the value of $ E ^\circ $ cell ?
