WebThe specific conductance (K) is given by K = (1/R) (l/a) as 1/R = C i.e. conductance K = C (l/a) l/a = K/C as l/a is constant called as ‘cell constant’ Cell constant = Specific conductance (ohm-1 cm-1 ) / measured … WebSo that would be positive .54 volts, so positive .54 plus 1.66, plus positive 1.66 volts. So the standard potential for the cell, so E zero cell is equal to .54 plus 1.66 which is equal to 2.20 volts. All right, now that we've found the standard cell potential, we can calculate the equilibrium constant. hilton statesboro georgia
