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.

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
