The standard reaction enthalpy for the decomposition of cacl2 · nh3(s) into cacl2(s) and nh3(g) is nearly constant at +78 kj mol−1 between 350.k and 470.k. the equilibrium pressure of nh3 in the presence of cacl2 · nh3 is 1.71 kp a at 400.k. find an expression for the temperature dependence of ∆rg◦ m in the same range.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
