Question

A non-conducting partition divides a container into two equal compartments. One is filled with helium gas at 400 K and the other is filled with carbon monoxide gas at 240 K. The number of molecules in each gas is the same. If the partition is removed to allow the gases to mix, then the final equilibrium temperature will be

Options:

Answer:

A

Solution:

Energy balance with equal $n : \frac{3 R}{2} (400) + \frac{5 R}{2} (240) = (\frac{3 R}{2} + \frac{5 R}{2}) T_{f}$ .

$T_{f} = \frac{600 + 600}{4} = 300 K .$

Energy balance with equal n : 2 3 R ​ ( 400 ) + 2 5 R ​ ( 240 ) = ( 2 3 R ​ + 2 5 R ​ ) T f ​ . T f ​ = 4 600 + 600 ​ = 300 K .
