A cell containing a standard Sn2+/Sn electrode and a standard Ag+/Ag electrode is constructed, and the circuit is closed. Potassium nitrate is used as a salt bridge. Without consulting the table of standard reduction potentials, diagram and completely describe the cell from the following experimental observations: i. the mass of the silver electrode decreases ii. the mass of the tin electrode increases Be sure to include the following: a. Label the anode and cathode b. Label the electrodes and the solutions c. Indicate the direction of electron flow d. Label the salt bridge and show the direction of anion/cation movement e. Write the half-reactions that occur at the anode and cathode f. Write the complete balanced equation for this reaction

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
