If the first step is slow and the second one is fast, what rate law do you expect to be observed for the overall reaction?

The  rate law of the first step

Explanation:

In reactions with multiple steps, teh overall reaction rate is ruled by the rate of the slower step. This is because the slower step creates an effect of "bottle neck" and it  doesn't matter how fast are the other steps.

For example, given:

If the production of B is the slow step, B is going to be consumed fast to produce C but you can't produce more C if you don't have B. So it doesn't matter the rate of production of C if you can produce B at the same rate.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
