The slowest step of a reaction mechanism is called the
a.) elementary step
b.) inhibitor
c.) rate law
d.) rate-determining step

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 .

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
