Using values from Appendix C of your textbook, calculate the value of \( K_{\text {eq }} \) at \( 298 \mathrm{~K} \) for each of the following reactions: (a) \( 2 \mathrm{~N}_{2} \mathrm{H}_{4}(9)+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{I}) \rightleftharpoons 4 \mathrm{NH}_{3}(\mathrm{~g})+\mathrm{O}_{2}(9) \) \[ \mathrm{K}_{\mathrm{eq}}= \] (b) \( 2 \mathrm{FeCl}_{3}(5)+3 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightleftharpoons \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+6 \mathrm{HCl}(9) \) \[ K_{\mathrm{tg}}= \] (c) \( \mathrm{N}_{2}(9)+3 \mathrm{H}_{2}(\mathrm{~g})=2 \mathrm{NH}_{3}(\mathrm{~g}) \) \[ \mathrm{K}_{\mathrm{eq}}= \]
