A dilute aqueous solution of calcium hydroxide at 25 Degree C reacts with gaseou

Question

A dilute aqueous solution of calcium hydroxide at 25 Degree C reacts with gaseous hydrogen chloride via the following reaction. If the hydrogen chloride enters the reactor at 88.0 Degree C, and the solution exits at 25 Degree C, how much heat must be removed for every mole of CaCI2 produced? The heat of solution of Ca(OH)2 is -1008.2 kJ/mol, the heat of formation of Ca(OH)2 is -985.65 kJ/mol, the heat of solution of CaCl2 is -875.07 kJ/mol and the heat of formation of CaCI2 is -797.46 kJ/mol. Number Q = kJ/mol

Explanation / Answer

heat of solution- Ca(OH)2 = -1008.2-(- 875.07) (for CaCl2 ) = 133.13

then heat needed to be removed for every mole of Cacl2 is 133.13
