A 20 litre container at 400 K contains CO_2(g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). The volume of the container is now decreased by moving the mavable piston fitted in the container. The maximumvolume of the conatiner, when pressure of CO_2 attains its maximum value will be : Give that : SrCO_3 (s)hArr SrO(s) + CO_2(g) K_p = 1.6 atm

1.	A 20 litre container at 400 K contains CO_2(g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). The volume of the container is now decreased by moving the mavable piston fitted in the container. The maximumvolume of the conatiner, when pressure of CO_2 attains its maximum value will be : Give that : SrCO_3 (s)hArr SrO(s) + CO_2(g) K_p = 1.6 atm
Answer» <P>2 litre 5 litre 10 litre 4 litre Solution :Given that `K_p = 1.6 atm` `V_1 = 20 L, V_2 = ?, T_1 = 400 K , T_2 = 400K` `K_P = P_(CO_2)` `:. P_(CO_2) = 1.6 atm` `P_1 = 0.4 atm` `P_2= 1.6 atm` `(P_1V_1)/T_1= (P_2V_2)/T_2` `:. V_2 = (P_1V_1)/T_1 xx T_2/P_2 =(0.4 atm xx 20L)/(cancel 400K) xx (cancel400K)/(1.6atm) = 5L`
