Answer :
Answer:
The correct answer is option A.
Explanation:
Total pressure of mixture = p = 378 kPa
Partial pressure of the oxygen gas = [tex]p^o_{O_2}=212 kPa[/tex]
Partial pressure of the hydrogen gas = [tex]p^o_{H_2}=101 kPa[/tex]
Partial pressure of the nitrogen gas = [tex]p^o_{N_2}=?[/tex]
As we know that total pressure is sum of partial pressures exerted by all the individual gases.
[tex]p=p^o_{O_2}+p^o_{H_2}+p^o_{N_2}[/tex]
[tex]378 kpa=212 kPa+101 kPa+p^o_{N_2}[/tex]
[tex]p^o_{N_2}=378 kPa - 212 kPa-101 kPa=65 kPa[/tex]
65 kPa the partial pressure exerted by nitrogen.

As we know that
P total = pO +pH +pN
so
P = P1 + P2 + P3
378 kPa= 212 kPa + 101 kPa + P(H2)
P(H2) = 65 kPa
partial pressure is 65
so correct option is A
hope it helps
