Two bulbs are connected with a tube of negligible volume. Bulb I has 2.8gN_2atT_1K .The other bulb(II) is completely evacuated. The bulb (I) is heated to T_2K while bulb (II) is maintained at T_2/3K . Volume of bulb (I) is half that of bulb (II). If the valve is opened, then what is the weight ratio of N_2 in both bulbs, (W_1/W_2) ?

The following electrochemical cell has been set up: Pt(1)|Fe^(3+),Fe(a=1)||Ce^(4+), Ce^(3+)(a=1)|Pt(2) . If an ammeter is connected between two platinum electrodes, predict the direction of the flow of current. Will the current increase or decreases with time ? Given: E_((Fe^(3+)|Fe^(2+)))^(@)=0.77V and E_((Ce^(4+)|Ce^(3+)))^(@)=1.61V
