Using the fact that at 0.10 M, the absorbance was 0.357; and at 0.20 M, the absorbance was 0.714, the absorptivity (slope) is Blank 1

(answer to 2 dec places). Using your absorptivity, if an absorption of 0.250 is measured, the concentration is

Blank 2

M (answer to 2 dec places)

The answer is "3.57 and 0.07".

Explanation:

Using the slop formula:

Given:

length path  

from calibration it is found that

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
