Consider the following representation of a reaction mechanism.
step 1: unimolecular (fast)
step 2: bimolecular (slow)
step 3: unimolecular (fast)
which conclusion about the rate law for the reaction above is reasonable?
a. it is first order overall because step 1 is unimolecular.
b. it is first order overall because both steps 1 and 3 are unimolecular.
c. it is second order overall because step 2 is bimolecular.

The correct answer is: D. It is second order overall because step 2 is bimolecular.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
