$2-16.$ The classic way to synthesize ammonia is through

the gas phase chemical reaction:

$N_2+3H_{2}2N{H}_3$

This reaction is carried out at high pressures, most

often using an iron catalyst.

A$.$ Use Equation $2\mathrm{.}32$ and $C_P^{*}$ from Appendix D to

determine the change in molar enthalpy when

nitrogen is compressed from $T=300K$ and $P=1$

bar to $T=700K$ and $P=200$ bar.

B$.$ Repeat part A for hydrogen.

C$.$ What assumptions or approximations were made

in step B$?$ Comment on how valid you think the

approximations are.
