Isotherms of carbon dioxide at various temperatures are repersented in figure. Answer the following questions based on this figures. (i) In which state will CO_(2) exist between the points a and b at temperature T_(1) ? (ii) At what point will CO_(2) start liquefyinh when temperature is T_(1) ? (iii) At what point will CO_(2) be completely liquefued when temperature is T_(2) ? (iv) Will condensation take place when the temperature is T_(3) ? (v) What portion of the isotherm at T_(1) represent liquid and gaseous CO_(2) at equilibrium ? |

Answer» `BARU =sqrt((8RT)/(piM))` In the present case, `baru =9.0xx10^4 " cm " s^(-1)`, `R=8.314xx10^7 " erg " K^(-1) mol^(-1)` `T=T_1 (?) and M=44` `:. "" 9.0xx10^4=sqrt((8xx8.314xx10^7xxT_1)/(3.14xx44))` HENCE, `T_1 = 1682.5 K`. The most probable velocity is given by `ALPHA = sqrt((2RT)/M)` `:. "" 9.0xx10^4=sqrt((2xx8.314xx10^7xxT_2)/(44))` Which gives `T_2 = 2143.3 K`. |
