In a mixture of 2 ideal gases, a and b, pa = 0.2pb, what is the mole fraction of a?

0.1667

Explanation:

Hello,

Dalton's law defines:

A total pressure is:

So, for A (solving for in the previous equation, we get:

Since , we obtain:

}

Best regards.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
