| a. \[CO(g)+{{H}_{2}}O(g)\underset{{}}{\overset{{}}{\longleftrightarrow}}C{{O}_{2}}(g)+{{H}_{2}}(g);{{K}_{1}}\] |
| b. \[C{{H}_{4}}(g)+{{H}_{2}}O(g)\underset{{}}{\overset{{}}{\longleftrightarrow}}CO(g)+3{{H}_{2}}(g);{{K}_{2}}\] |
| c. \[C{{H}_{4}}(g)+2{{H}_{2}}O(g)\underset{{}}{\overset{{}}{\longleftrightarrow}}C{{O}_{2}}(g)+4{{H}_{2}}(g);{{K}_{3}}\] |
| Which of the following relations is correct? |
A) \[{{K}_{3}}={{K}_{1}}{{K}_{2}}\]
B) \[{{K}_{3}}\,.\,\,K_{2}^{3}=K_{1}^{2}\]
C) \[{{K}_{1}}\sqrt{{{K}_{2}}}={{K}_{3}}\]
D) \[{{K}_{2}}{{K}_{3}}={{K}_{1}}\]
Correct Answer: A
Solution :
\[\begin{align} & CO(g)+{{H}_{2}}O(g)C{{O}_{2}}(g)+{{H}_{2}}(g);{{K}_{1}} \\ & C{{H}_{4}}(g)+{{H}_{2}}O(g)CO(g)+3{{H}_{2}}(g);{{K}_{2}} \\ \end{align}\] \[C{{H}_{4}}(g)+2{{H}_{2}}O(g)C{{O}_{2}}(g)+4{{H}_{2}}(g)\] \[;{{K}_{3}}={{K}_{1}}\times {{K}_{2}}\]
