If a chemical process is affected by more than one factors then its rate will be determined by 

a) 
Two closely related factors 
b) 
Only one factor, which is close to its minimal value 
c) 
Only one factor, which is close to its maximum value 
d) 
Only one factor, which is close to its appropriate value

d) 
Only one factor, which is close to its appropriate value 
(b) Only on factor, which is close to the minimal value. Law of limiting factor was proposed by F. F. Blackman. (1905). It stated that when a process is conditioned as to its rapidly by number of separate factors, the rate of the process is limited by the pace of the slowest factor (i.e., the factor present in minimum amount)
