\[{{H}_{2}}O\left( 1,323\text{ }K \right)\xrightarrow{{}}{{H}_{2}}O\left( g,423K \right)\] |
Given: \[{{C}_{v,m}}({{H}_{2}}O,I)=75.0J{{K}^{-1}}mo{{l}^{-1}}\]; |
\[{{C}_{p.m}}({{H}_{2}}O,g)=33.314J{{K}^{-1}}mo{{l}^{-1}}\] |
\[\Delta {{H}_{vap}}\,\text{at}\,373\,K=40.7\,kJ\text{/}mol\] |
A) \[42.91\text{ }kJ/mol\]
B) \[43086\text{ }kJ/mol\]
C) \[42.6\text{ }kJ/mol\]
D) \[49.6\text{ }kJ/mol\]
