Question

What will be the pressure of the gaseous mixture when 0.5 L of H₂ at 0.8 bar and 2.0 L of dioxygen at 0.7 bar are introduced in a 1L vessel at 27°C?

Answer 1

Let the partial pressure of H₂ in the vessel be.

Now,

= ?

It is known that,

Now, let the partial pressure of O₂ in the vessel be.

Total pressure of the gas mixture in the vessel can be obtained as:

Hence, the total pressure of the gaseous mixture in the vessel is.
