Answer:
Explanation:
Hello,
At the specified conditions, to compute the released heat due to the mixing process, which also includes the effect of the reaction enthalpy, we take into account the following formula:
All of the terms listed above are considered as changes. Thus, the enthalpy due to the water heating turns out into:
Now, it is found that the enthalpy of the carried out reaction:
Has a value of -56.72kJ/mol but as 0.5 mol are involved, the total enthalpy turns out into -28.5kJ
Now, that reaction enthalpy is by far higher than the enthalpy due to the temperature increasing, thus, one concludes that the total released enthalpy is negative and has a value of:
Best regards.
