Using your experimental data and Hes's law, what is the enthalpy of reaction for NaOtH (s) NaOH (aq)? b. Is this reaction endothermic or exothermic? 8-12 CHEM1414-AY 2017-2018

Explanation / Answer

SOLUTION:

1.Some data missing in question

We have to write the reaction between them first:

NaOH + HCl -----> NaCl + H2O

this equation always shows the relation in moles

1 mol NaOH reacts with 1 mol HCl to form 1 mol NaCl

moles can be obtained = mass/ molar mass

or moles = molarity x volume in litres

2.

We need to find the heat released per mole by looking at the change in temperature of solution

mCpT = heat absorbed by solution

from here heat of neutralization can be obtained

mCpT = H x n

n = no. of moles of NaOH reacted

H = molar heat of neutralization

Cp = heat capacity of water
