The cell would therefore proceed spontaneously in Case 2.Notice that we did not multiply the value for the reduction potential of I 2 by a factor of 2, even though the iodine reduction equation would be multiplied by this factor to balance the number of electrons produced and consumed. The standard cell potential for the reaction is then +0.34 V – (-0.76 V) = +1.10 V. The polarity of the cell is determined by knowing that zinc metal is a stronger reducing agent than copper metal. Therefore, the standard reduction potential for zinc is more negative than that of copper. Standard electrode potential (data page) A temperature of 298.15 K (25.00 °C; 77.00 °F). An effective concentration of 1 mol/L for each aqueous species or a species in a mercury amalgam (an alloy of mercury with another metal). A partial pressure of 101.325 kPa (absolute) (1 atm, 1.01325 bar) for The standard cell potential is positive, so the reaction is spontaneous as written. Tin is oxidized at the anode, while silver ion is reduced at the cathode.

This one says the cell has a standard cell potential of point of positive. So we want our cell potential. So that's e no.

All standard potentials are reduction potentials that are they refer to a reduction reaction. The cathode has a higher standard potential than the anode. For spontaneous reaction to take place the cell potential should be positive.

In an electrochemical cell, an electric potential is created between two dissimilar metals. This potential is a measure of the energy per unit charge which is available from the oxidation/reduction reactions to drive the reaction. this video explain the concept of standard cell potential i.e standard oxidation & reduction cell potential in hindi.• for my handwritten notes :- https The standard cell potential for the reaction is then +0.34 V – (-0.76 V) = +1.10 V. The polarity of the cell is determined by knowing that zinc metal is a stronger reducing agent than copper metal. Therefore, the standard reduction potential for zinc is more negative than that of copper. Either Standard reduction potential or standard oxidation potential can be calculated for an electrode using standard hydrogen electrode. Standard cell potential is the difference between standard reduction potentials of two half – cells or half – reactions.
