5. The reaction: is first order in both directions. At 25℃ the equilibrium constant is 0.16 and the rate constant k, is. In an experiment starting with the pure trans form, how long would it take for quarter the equilibrium amount of the cis isomer to be formed?(20%)

||3. The volume of an aqueous solution of NaCl at 25℃ was measured at a series of molalities b, and it was found that the volume fitted the expression:where V (cm3) is the volume of a solution formed from 1.000 kg of water and x = b / bθ. Calculate the partial molar volume of the components in a solution of molality 0.100 mol. (20%)
