A binary mixture of oxygen and nitrogen with partial pressures in the ...
Given:
Partial pressure of oxygen (PO2) = 0.21 * (1 * 10^5 N/m^2)
Partial pressure of nitrogen (PN2) = 0.79 * (1 * 10^5 N/m^2)

To find:
Molar fraction of nitrogen (XN2)

Formula:
Partial pressure of a component = Molar fraction of the component * Total pressure of the mixture

Calculation:
Let XN2 be the molar fraction of nitrogen.
Since the total pressure of the mixture is the sum of the partial pressures of oxygen and nitrogen, we have:

PO2 + PN2 = 1 * 10^5 N/m^2

Substituting the given values:
0.21 * (1 * 10^5) + 0.79 * (1 * 10^5) = 1 * 10^5

Simplifying the equation:
0.21 * (1 * 10^5) + 0.79 * (1 * 10^5) = 1 * 10^5
0.21 * 10^5 + 0.79 * 10^5 = 10^5
0.21 + 0.79 = 1

This equation is satisfied, so the given values are correct.

Conclusion:
The molar fraction of nitrogen (XN2) is 0.79, which is option 'A'.
