What is the heat of solution (q soln) for the neutralization reaction between NH3 and HCl? (NH 4) 2 CO 3 NH 4 HCO 3 + NH 3 On heating strongly above 340 degree C, the white solid ammonium chloride, thermally decomposes into a mixture of two colourless gases ammonia and hydrogen chloride. 42 4 + ++ + + Figure 6 presents the ammonium chloride desublima- tion temperature as a function of the reaction column humidity at 2 MPa. Consider the decomposition of ammonium chloride at a certain temperature:$$\mathrm{NH}_{4} \mathrm{Cl}(s) \rightleftarrows \mathrm{NH}_{3}(g)+\mathrm{HCl}(g)$$Calculate the equilibrium constant $K_{P}$ if the total pressure is $2.2 \mathrm{~atm}$ at that temperature. The enthalpy change of the overall process is the sum of the enthalpy changes of its individual steps and does not depend on the route taken.
