Aqueous HCl can be manufactured by gas-phase reaction of H2 and Cl2 to form HCl(g), followed by absorption of HCl(g) with water. Consider a steady-state process at 25°C where HCl(g)
and pure water are fed to form aqueous acid with 30% HCl by weight. What is the amount of cooling that must be provided per mole of product produced?
