Answer : The enthalpy change for the solution is 42.8 kJ/mol
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water = 100.0 g
= change in temperature =
Now put all the given values in the above formula, we get:
(1 kJ = 1000 J)
Now we have to calculate the enthalpy change for the solution.
where,
= enthalpy change = ?
q = heat released = 3.5138 kJ
m = mass of NaOH = 3.25 g
Molar mass of NaOH = 40 g/mole
Now,
Therefore, the enthalpy change for the solution is 42.8 kJ/mol
