Problem

The density of an equilibrium mixture of

\text{N}_2\text{O}_4

and

\text{NO}_2

1 \text{ atm}

3.62 \text{ g/litre}

288 \text{ K}

and

1.84 \text{ g/litre}

348 \text{ K}

. Calculate the enthalpy of reaction :

\text{N}_2\text{O}_4 \rightleftharpoons 2\text{NO}_2

. Also calculate the entropy change during the reaction at

348 \text{ K}
