Consider the following representation of a reaction mechanism.
step 1: a + a > c + e (slow)
step 2: e + b > a + d (fast)
overall reaction: a + > c + d
what should appear in the rate law for the reaction above?

only a and b because they are reactants in the overall reaction
only c and c because they are products in the overall reaction
only a because it is the reactant in the rate-determining step
only e and b because they are the reactants in the rate-determining step

the answer is true. hope it .

is there any options? maybe im just not seeing them but i need the options to

-love shrooms

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
