Use the Following Data to Calculate the Enthalpy Change for the Following

question 17

Short Answer

Use the following data to calculate the enthalpy change for the following reaction: $$\begin{array} { l c } { 2 \mathrm { Na } ( \mathrm { s } ) + \frac { \mathrm { 1 } } { 2 } \mathrm { O } _ { 2 } ( g ) } \rightarrow \mathrm { Na } _ { 2 } \mathrm { O } ( s ) \\\text { Quantity } & \text { Magnitude } ( \mathbf { k J } / \mathbf { m o l } ) \\\text { Ionization energy of } \mathrm { Na } ( g ) & 495 \\\text { Electron affinity of } \mathrm { O } ( g ) \text { for } 2 \mathrm { e } & 603 \\\text { Vaporization energy of } \mathrm { Na } ( s ) & 109 \\\text { Bond energy of } \mathrm { O } _ { 2 } ( g ) & 499 \\\text { Lattice energy for } \mathrm { Na } _ { 2 } \mathrm { O } ( s ) & - 2,477\end{array}$$
