Answer to Question #188024 in Physical Chemistry for ANIL MATHEW SONNY

Question

In a calorimeter was mixed 40 g of 0.6 mol / L HCl solution and 40 g of 0.5 mol / L NaOH solution. Before mixing the initial temperature of both solutions was 25ºC and when the reaction was complete the temperature was 28.0ºC. Using the c(water) = 4.18 Jg^-1K^-1 calculate the enthalpy (ΔH, kJ / mol) of the reaction of NaOH solution with HCl solution.

Answer 1

Enthalpy of the reaction;

$=-54Jg/K$
