The conductivity probe measures current flow. It consists of two electrodes: one electrode is positively-biased, and the other is negatively-biased. Which respective directions do cations and anions flow when being measured?

options:

1) Both cations and anions flow to the positive electrode.

2) Both cations and anions flow to the negative electrode.

3) Cations flow to the negative electrode, and anions flow to the positive electrode.

2b2t

explanation:

2b2t

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

the answer is symmetrical : )
