Abscissae represents exposure in minutes; ordinates per cent, of total cyanide. ture, a curve was obtained as indicated in Fig. 7. The rate repre- sents the time when the intracellular concentration of cyanide is twenty-five per cent, of the external concentration. It will be seen from this figure that there is a break in the line at 16° C. (.003415). Calculating Q from the Vant Hoff-Arhenius equa- tion, (26) K*/Ki = Q/2 I T • T2 a value of 11,179 is obtained at a temperature from 16° C. to and 4,300 for o° to 16°..
