A) \[~-68,000\text{ cal}\]
B) \[~-67,800\text{ cal}\]
C) \[~-67,050\text{ cal}\]
D) \[~+\,68,500\text{ cal}\]
Correct Answer: A
Solution :
\[CO(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}C{{O}_{2}}(g)\] \[\Delta H=\Delta E+\Delta nRT\] \[\Delta H=-67,710-\frac{1}{2}\times 2\times 290\] \[=-68000\,\text{cal}\]You need to login to perform this action.
