Ответ:
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
Ответ:
The correct answer is option A.
Explanation:
Total pressure of mixture = p = 378 kPa
Partial pressure of the oxygen gas =
Partial pressure of the hydrogen gas =
Partial pressure of the nitrogen gas =
As we know that total pressure is sum of partial pressures exerted by all the individual gases.
65 kPa the partial pressure exerted by nitrogen.
