Nitrogen fixation is the process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria. The process is undertaken by the rhizobium bacteria that live in root roots of plants such as legumes. The mutualistic relationship is that the plant supplies the bacteria with a habitat in which to live, water, and nutrients, and the bacteria supply nitrogen for making plant proteins.
Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:

Relation of
with
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles =
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
According to the basic facts, the only one non-charged subatomic particle from the scale is definitely neutrons because protons is always positively charged whereas elecrtons is <span>negatively charged. So, the right answer is A.</span>
