In order to verify the heat of reaction, a chemist mixes 1 liter of 1 M NaOH and 1 liter of 1 M HCl. The initial temperature of the two solutions is 25C. The specific heat of water is 4.184 J/gC. The enthalpy of reaction of the following is –58 kJ/mol. HCl(aq) + NaOH(aq) = NaCl(aq) + H2O(l) Is this reaction exothermic or endothermic? (Will the temperature increase or decrease?) Considering only the specific heat of the 2 liters of water and no heat transfer to/from surroundings, what is the final temperature of the solution (notice that the specific heat is in terms of mass, not volume)?
Please explain.
Thank you
