One mechanism for the synthesis of ammonia proposes that N₂ and H₂ molecules catalytically dissociate into atoms:(c) How many N atoms and H atoms are present per liter?

A catalyst is a material that, without being consumed by the process, speeds up a chemical reaction or decreases the temperature or pressure required to initiate one. The addition of a catalyst to a reaction is known as catalysis.

Ideal gas law is given below:

PV=nRT

Here, P is pressure, V is volume, n is the number of moles of gas, R is the universal gas constant, and T is temperature.

Calculate moles of N formed from its partial pressure (4 * 10 to power -21) and volume 1 L

n(N) = Pn.V/RT

= ( 4 * 10 to power -21)(1L)/(0.08206L atm mol to power -1 K to power -1)(1000K)

= 4.9 * 10 to power -23 mol

To find atoms of N multiply n with Avogadro's number,

Number of N atoms = nN * 6.022 * 10 to power 23 N atoms/ mol N

Number of N atoms = 4.9 * 10 to power -23 mol N * 6.022 * 10 to power 23 N atoms/ mol N

Thus, the number of N atoms in a liter is 29.5 atoms.
