Question

Two vessels connected by a valve of negligible volume. One container (I) has 2.8 g of N2 at termperature T1(K). The other container (II) is completely evacuated. The container (I) is heated to T2 (K) while container (II) is maintained at T23 (K). volume of vessel (I) is half that of vessel (II). If the valve is opened then what is the weight ratio of N2 in both vessel (WI/WII)?

Solution

The correct option is C 1:6

Let x mole of N2 present in vessel II and P is final pressure of N2
P(2V)=xR(T23) ...(1) P(V)=(0.1x)RT2 ...(2)
Dividing the equation 1 by equation 2, we get
2=x3(0.1x)
x=0.6/7 mole;
0.67×282.4 g N2
II has 2.4 g N2 and I has 0.4 g of N2
WIWII=0.42.41:6
