can you give me an explanation to this question what is mean by kinetics of complex reaction?

@ annie 
Kindly be specific in asking your query . i mean a little bit descriptive . 
kinetics means the study of rate of decomposition , rate of formation , time taken to complete the reaction , the reagents involved etc . 
and as far as complex reactions are concerned , then complex reaction means the reaction which will happen in more than 2 steps ,
and in that case the rate u have to decide with the slowest step of the reaction /. 
and kinetics of complex reaction means study the rate , in which the reaction is happening in more than 2 steps . 
HOPE IT CLEARS TO YOU NOW , 
IF ANY MORE DOUBT DO GET BACK TO US .
