(c) Sodium reacts with nitrogen to form sodium nitride.
Complete the equation for this reaction.
\[
6 \mathrm{Na}_{a}+\mathrm{N}_{2} \rightarrow 2^{\mathrm{ma}_{3} \mathrm{~N}}
\]
When carbon is heated with steam in a closed container an equilibrium mixture is formed
\[
\mathrm{C}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{~g}) \rightleftharpoons \mathrm{CO}(\mathrm{~g})+\mathrm{H}_{2}(\mathrm{~g})
\]
The forward reaction is endothermic.
(i) Describe and explain the effect, if any, on the position of equilibrium when the temperature
