JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Topic Test - Chemical Equilibrium (6-5-21)

  • question_answer
    \[\Delta {{G}^{0}}(HI,\,g)\cong +1.7\,kJ\]. What is the equilibrium constant  at \[{{25}^{o}}C\] for \[2HI(g)\] D \[{{H}_{2}}(g)+{{I}_{2}}(g)\]

    A) 24.0     

    B) 3.9

    C) 2.0

    D) 0.5

    Correct Answer: D

    Solution :

    [d] \[\Delta {{G}^{o}}=-2.303\times 8.314\times {{10}^{-3}}\times 298\,\,\log \,{{K}_{p}}\]
             \[1.7=-2.303\times 8.314\times {{10}^{-3}}\times 298\times \log \,{{K}_{p}}\]
