A) 40.0
B) 42.3
C) 44.0
D) Not defined because pressure is not constant
Correct Answer: C
Solution :
\[\Delta H={{H}_{2}}-{{H}_{1}}=\left( {{E}_{2}}+{{P}_{2}}{{V}_{2}} \right)-\left( {{E}_{1}}+{{P}_{1}}{{V}_{1}} \right)\] \[=({{E}_{2}}-{{E}_{1}})+({{P}_{2}}{{V}_{2}}-{{P}_{1}}{{V}_{1}})\] \[=30+\left( 4\times 5-2\times 3 \right)=44L\]atmYou need to login to perform this action.
