positive

Because the heat is absorbed by the system, the 177.8 kJ is written as a reactant. The heat of reaction is positive for an endothermic reaction.

A student needs to find out how much heat is released or absorbed when 100 mL of 0.1 mol/L solution of barium chloride (BaCl2) is mixed with 150 mL of 0.1 mol/L solution of sodium sulfate (Na2SO4) at 25°C. Given the enthalpy of precipitation of BaSO4 as -256 kJ/mol, calculate the enthalpy change (in kJ) for the reaction that occurs and determine whether the reaction is exothermic or endothermic.
