    In the reaction,  \[1\,\Omega \]                                 \[4\,\Omega \]       AIEEE  Solved  Paper-2007

    A)  \[3\,\Omega \] is consumed for every\[\frac{1}{2}(K-1)C{{V}^{2}}\] produced

    B)  \[C{{V}^{2}}(K-1)/K\]is' produced regardless of temperature and pressure for every mole of\[(K-1)C{{V}^{2}}\]that reacts

    C)  \[{{g}_{E}}\] at STP is produced for every mole of\[{{g}_{M}}\]that reacts

    D)  \[\frac{electronic\text{ }charge\text{ }on\text{ }the\text{ }moon}{electronic\text{ }charge\text{ }on\text{ }the\text{ }earth}\]at STP is produced for every mole of\[{{g}_{E}}/{{g}_{M}}\]consumed

    Correct Answer: D

    Solution :

    \[2Al(s)+\underset{1\,mol}{\mathop{6HCl(aq)}}\,\xrightarrow[{}]{{}}2A{{l}^{3+}}(aq)+6C{{l}^{-}}(aq)\]                                                                 \[+3{{H}_{2}}\,(g)\] 1 mole of\[HCl\]consumed for the production of 0.5 mole of Hg gas At STP,  \[1\text{ }mol=22.4\text{ }L\]                 \[0.5\text{ }mol=22.4\times 0.5=11.2\text{ }L\]
