A) -110.5 kJ
B) 676.5 kJ
C) -676.5 kJ
D) 110.5 kJ
Correct Answer: A
Solution :
\[C+\frac{1}{2}\,{{O}_{2}}\,\,\to \,\,CO\] \[\Delta H={{\left( \sum {{H}_{comb}} \right)}_{R}}-{{\left( \sum {{H}_{comb}}. \right)}_{P}}\] \[=\text{ }\left( -393.5 \right)-\left( -283 \right)\] \[=\,\,\,-110.5\,\,kJ\]You need to login to perform this action.
