OPTICAL ACTIVATION 



DECOMPOSITION OF BROMCAMPHOII-CARBOXYLIC ACID. 



1. Experiment^ Without Catalysts and Temperature Co- 

 efficient. 



The decomposition of bromcamphor-carboxylic acid in 

 acetophenone, in the absence of alkaloids, was found to follow 

 the first order of reaction, -the velocity constant being calculated 

 from the equation 



k = 



1 



A 



t '0,4843 A-x' 



The symbols here have the same meaning as previously 

 indicated. 



The values obtained for It at 80, 70, and 60 are as 

 follows :
