Answer:
[The dilution of 4 M solution in 1000 L is done to 2M. The enthalpy change is -2.5 kJ/mol. When 500 mL of HCl is diluted from 4M to 2M, the enthalpy change will be the same as the enthalpy change does not depend on temperature. Thus, enthalpy change on diluting 500 mL of HCl from 4M to 2M is -2.5 kJ/mol.]
