1.	Consider the composite system, which is held at 300 k , shown in the following figure. Assuming ideal gas behavior, calculate the total pressure if the barriers sparating the compartments are removed. Assume that the volume of the barriers is negligible. (Given : R =0.082 atm L/mol. K) A. 1 atmB. 2 atmC. 2.3 atmD. 3.2 atm
Answer» Correct Answer - b (b) The number of moles of He, Ne and Xe is given by `n_(He)=(PV)/(RT)=(3)/(RT)," "n_(Ne)=(PV)/(RT)=(10)/(RT),` `n_(Xe)=(PV)/(RT)=(1)/(RT),` `n=n_(He)+n_(Ne)+n_(Xe)=((3+10+1))/(RT)` The total pressure is given by `P=((n_(He)+n_(Ne)+n_(Xe))RT)/(V)` `P_("total")=((3+10+1))/(RT)xx(RT)/(7)=2atm`
