proportion of these substances when there is equilibrium will be altered by passing an 
electric current through the solution. Thus the coefficient of reaction u will be altered, 
and we see from equation (56) that the alteration Sw is given by the equation

where the notation is the same as that used on page 509. 
Thus, if the specific resistance increases as any reaction goes on, the passage of an 
electric current through the solution will tend to stop that reaction.
