A student poured 100 ml of water into a coffee calorimeter, noted that the temperature of the water was 24.9°C, then added 6.664 g LiCl. With the lid on,
the mixture was stirred, temperature increased and the maximum temperature reached 37.9 °C.
Calculate the molar enthalpy change of reaction (AHº) in kJ per mole of salt. qsys = -5796.1 J. (You have 2 attempts until the answer will be given; you
have already tried 1 times)
AHO for dissolution of LiCl =
SUBMIT
kJ mol-1
