curve shown in the figure, while if K^ is less than K2 we 

 get the lower curve (in the latter case both outlets are 

 supposed to be smaller than in the former). This is 

 analogous to what occurs in the reaction A — *-M — >-B 

 if K^ is the velocity constant of J^ — >M and K2 is the 

 velocity constant of M — >B. 



We assume that in sea water A is renewed as fast

 that M has the constant value 90. On transferring from 

 sea water to NaCl 0.52 M the production of A ceases, but 

 A continues to break down to form M and B. The velocity

 We may now calculate the resistance, putting Net
