A) \[-869.6\,kJ\]
B) \[+\,434.8\,kJ\]
C) \[+\,217.4\,kJ\]
D) \[-\,434.8\,kJ\]
Correct Answer: B
Solution :
\[4H(g)\xrightarrow[{}]{{}}2{{H}_{2}}(g);\Delta H=-869.6\,\text{kJ}\] \[2{{H}_{2}}(g)\xrightarrow[{}]{{}}4H(g);\Delta H=869.6\,\text{kJ}\] \[{{H}_{2}}(g)\xrightarrow[{}]{{}}2H(g);\Delta H=\frac{869.6\,}{2}=434.8\,\text{kJ}\]
