Answer : The enthalpy of this reaction is, 1.06 kJ/mol
Explanation :
First we have to calculate the heat produced.
where,
q = heat produced = ?
m = mass of solution = 137 g
c = specific heat capacity of water =
= initial temperature =
= final temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy of this reaction.
where,
= enthalpy change = ?
q = heat released = 2.12 kJ
n = moles of compound = 2.00 mol
Now put all the given values in the above formula, we get:
Thus, the enthalpy of this reaction is, 1.06 kJ/mol
