• # 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

 [d] $\Delta {{G}^{o}}=-2.303\times 8.314\times {{10}^{-3}}\times 298\,\,\log \,{{K}_{p}}$ $1.7=-2.303\times 8.314\times {{10}^{-3}}\times 298\times \log \,{{K}_{p}}$ ${{K}_{p}}=0.5$
