A fixed chamber isolated from surrounding is divided into equal halves A and B as shown in figure. Part A contains one mole of oxygen and part B contains one mole of helium. The separator C is thermally conducting and kept fixed. Initial temperature of oxygen chamber is 600 K and that of helium 300 K. Specific heat capacity of separator and chamber is negligible. Choose the correct statement.

Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature T_0 , while box B contains one mole of helium at temperature 7/3T_0 . The boxes are then put into thermal 3 contact with each other and heat flows between them until the gases reach a common final temperature. (Ignore the heat capacity of boxes). Then, the final temperature of the gases, T_f in terms of T_0 is ____
