Question

A dilute aqueous solution of calcium hydroxide at 25°C reacts with gaseous hydrogen chloride via the following reaction. 2HCI(g) + Ca(OH),lag, r=-) → Caci,lag, r= 0)+2H, 0(1) If the hydrogen chloride enters the reactor at 71.0°C, and the solution exits at 25°C, how much heat must be removed for every mole of CaCl2 produced? The heat of solution of Ca(OH)2 is -1008.2 kJ/mol, the heat of formation of Ca(OH)is-985.65 kJ/mol, the heat of solution of CaCl2 is -875.07 kJ/mol and the heat of formation of CaCl2 is -797.46 kJ/mol. Number Q- 0 kJ/mol
