Question

2 litre He gas at 2 atm and 300 K is inserted into a 4 litre rigid container containing N₂ at 600 K and 4 atm. Finally mixture is maintained at 600 K temperature. The final pressure of gaseous mixture would be ______ torr.

Options

• 1269

• 6302

• 4560

• 5698

Answer 1

2 litre He gas at 2 atm and 300 K is inserted into a 4 litre rigid container containing N₂ at 600 K and 4 atm. Finally mixture is maintained at 600 K temperature. The final pressure of gaseous mixture would be 4560 torr.

Explanation:

`"n"_"He" + "n"_("N"_2) = "n"_"mixture"`

`(2 xx 2)/("R" xx 300) + (4 xx 4)/("R" xx 600) = ("P" xx 4)/("R" xx 600)`

P = 6 atm

= 6 × 760

= 4560 torr
