Problem

Hydrazine reacts with oxygen according to

\text{N}_2\text{H}_4(l) + \tfrac{1}{2}\,\text{O}_2(g) \rightarrow \text{N}_2(g) + 2\,\text{H}_2\text{O}(l)

\Delta H = -622\,\text{kJ mol}^{-1}

(per mole of

\text{N}_2\text{H}_4

). During a test firing,

1.24\times10^{3}\,\text{kJ}

of heat are released at

25\,^{\circ}\text{C}

and

1\,\text{atm}

. Determine the volume of

\text{N}_2(g)

produced under these conditions. (Assume ideal-gas behavior; molar volume at

25\,^{\circ}\text{C}

and

1\,\text{atm}

24.5\,\text{L mol}^{-1}
