Question 20

The equation for the reaction of sulfuric acid with sodium hydroxide is shown below:

\text{H}_2\text{SO}_4(\text{aq}) + 2\text{NaOH}(\text{aq}) \rightarrow \text{Na}_2\text{SO}_4(\text{aq}) + 2\text{H}_2\text{O}(\text{l})

A volume of 50 cm³ of 0.80 mol dm^-3 $H2SO4\text{H}_2\text{SO}_4$ is reacted with excess $NaOH\text{NaOH}$ . The energy given out is 4.56 kJ. What is the enthalpy change of neutralisation, in $mol−1\text{kJ mol}^{-1}$ ?

$- 57.0$

$- 114.0$

$- 28.5$

$- 228.0$
