To save money on camp canister refueling, you stop by a local plant that produces isobutane.

At this plant, $n-$butane is converted to isobutane in a continuous reactor that operates

isothermally at $149C.$ The stoichiometric butane isomerization reaction $($transformation of a

molecule into a different isomer$)$ is:

$n-C_4{H}_{10}(g)i-C_4{H}_{10}(g)$

The feed to the real reactor contains $35\%$ n$-$butane, $60\%$ isobutane, and $5\%HCl$ by mole. The

plant operators you speak with on your visit tell you that this process achieves $20\%$ conversion

of $n-$butane.

a$)$ Determine the standard heat of reaction of the isomerization reaction, $widehat(H{)}_r[k\frac{J}{m}ol].$

Using a basis of $10mo\frac{l}{m}in$ of feed gas to the reactor, calculate:

b$)$ molar flow rates, $n^{},$ of each feed and product component and the extent of reaction, ${}^{}$

$[mo\frac{l}{m}in$

c$)$ how many minutes it takes to fill your camp fuel canister with $450g$ of isobutane product

Using the feed and product species at $25C$ as references,

d$)$ Make a table that summarizes $n^{}[mo\frac{l}{m}in]$ and widehat$(H)[k\frac{J}{m}ol]$ for $n-$butane and isobutane in

and out. Use Table B$2$ to determine widehat$(H{)}_{in}$ and widehat$(H{)}_{\text{o}\text{u}\text{t}}$

e$)$ What heat transfer rate, $Q^{},$ is required to or from the reactor? Is the reaction endo$-$ or

exothermic?
