Suppose 3 different experimental runs with varying concentrations of initial reactants were conducted. The time for each run to reach the concentration of I2 determined in problem number 3 was measured and recorded as follows: Run #1 8 minutes 45 seconds, Run #2 5 minutes 14 seconds, and Run #3 3 minutes 27 seconds. Determine the average rate of each experimental run in [I2]/s.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
