A) \[\Delta H=0,\,\Delta V=10\left[ 1-{{\left( \frac{4}{3} \right)}^{3/2}} \right]\]
B) \[\Delta H=250\,\,RJ\,\,mo{{l}^{-1}},\,\Delta V=-10{{\left( \frac{3}{4} \right)}^{3/2}}\]
C) \[\Delta H=0,\,\,\Delta V=-10{{\left( \frac{4}{3} \right)}^{3/2}}\]
D) \[\Delta H=-250\,RJ\,mo{{l}^{-1}},\,\Delta V=10\left[ 1-{{\left( \frac{3}{4} \right)}^{3/2}} \right]\]
Correct Answer: C
Solution :
[c] Isothermal reversible compression \[\Delta T=0,\] \[\Delta U=0,\] \[\Delta H=0\] \[\Delta V={{\left( \frac{{{T}_{1}}}{{{T}_{2}}} \right)}^{{{C}_{v,m/R}}}}({{V}_{1}}-{{V}_{2}})\] \[={{\left( \frac{400}{300} \right)}^{3/2}}(-10L)=-10{{\left( \frac{4}{3} \right)}^{3/2}}\]You need to login to perform this action.
