Question

True or false? If false, please state why.

(a) If a solute partly dimerizes in a solvent, the freezingpoint depression is less than it would be if the solute did not dimerize.  

(b) Increasing the activity of a product in the cell’s chemical reaction must increase the cell potential.

(c) When a halfreaction is multiplied by 2, its standard reduction potential is multiplied by 2.

(d) For a binary twophase system, the closer the point on a tie line is to a phase, the less of that phase is present.

(e) A system at equilibrium with substances i and k present in one phase must have (i) = (k).
