QUESTION $2$

Pick ONE gas forming reaction for the following questions.

$H_{2}C{O}_{3(aq)}{H}_2{O}_{(l)}+C{O}_2(g)$

$N{H}_{4}O{H}_{(aq)}{H}_2{O}_{(I)}+N{H}_3(g)$

a$)$ Using the enthalpies of bond energies provided in the chart, what is the enthalpy of the reaction?

b$)6\mathrm{.}85$mol of gas is formed at $1\mathrm{.}05$atm in a $250mL$ flask. At what temperature does this formation occur?

c$)$ Convert the temperature you found in $b$ to Fahrenheit.

d$)$ If the gas from question b was transfered to a $1\mathrm{.}5L$ flask, what would be the new pressure?

e$)$ Convert the pressure in $d$ to units of $mmHg.$

f$)$ Comparing the gas products in the reaction you picked to the reaction you did NOT pick, which gas would effuse first?

g$)$ What are the assumptions do we make when we consider a gas "ideal"?

h$)$ Using the enthalpies of formation provided in the table at $25C,$ what is the enthalpy of the reaction?

Single Bond Energies $(k\frac{J}{m}ol$ of bonds$)$
