The decomposition of ozone in the upper atmosphere to dioxygen occurs by a two-step mechanism. The first step is a fast reversible step and the second is a slow reaction between an oxygen atom and an ozone molecule:Step 1: O3(g) O2(g) + O(g) Fast, reversible, reactionStep 2: O3(g) + O(g) → 2O2(g) SlowWhich is the rate determining step?

Step 2 in the given mechanism is the rate determining step

Explanation:

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

The intermediate reaction of the mechanism follows:

Step 1:  

Step 2:  

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

Hence, step 2 in the given mechanism is the rate determining step

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.

if it's not useful, feel free to report for mistake in answer.
