Answer:
D.) Rate-Determining Step
Explanation:
Rate - Determining Step -
The slowest step of any of the chemical reaction helps to find the overall rate of the chemical reaction , and , hence is known as the rate - determining step .
There are two type of reaction possible , one is elementary reaction and a complex reaction .
Elementary reaction is a single step reaction , and hence , that very step determined the rate of the reaction and hence is known as the rate determining step .
And ,
In case of a complex reaction , the reaction is preceded by many steps , and hence , the slowest step among other steps is known as the rate determining step of the reaction .
