Answer:

The correct answer is option A.

Explanation:

Total pressure of  mixture = p = 378 kPa

Partial pressure of the oxygen gas = p^o_{O_2}=212 kPa

Partial pressure of the hydrogen gas = p^o_{H_2}=101 kPa

Partial pressure of the nitrogen gas = p^o_{N_2}=?

As we know that total pressure is sum of partial pressures exerted by all the individual gases.

p=p^o_{O_2}+p^o_{H_2}+p^o_{N_2}

378 kpa=212 kPa+101 kPa+p^o_{N_2}

p^o_{N_2}=378 kPa - 212 kPa-101 kPa=65 kPa

65 kPa the partial pressure exerted by nitrogen.

As we know that

<span>P total = pO +pH +pN</span>

<span>so</span>

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
