Multiple Choice

Write a balanced chemical equation which corresponds to the following equilibrium constant expression.
$K = \frac { \left[ \mathrm { NO } _ { 2 } ^ { - } \right] \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] } { \left[ \mathrm { HNO } _ { 2 } \right] }$

• A) HNO₂(aq) + H₂O( \(\ell\) ) \(\rightleftharpoons\) NO₂^-(aq) + H₃O⁺(aq)
• B) NO₂^-(aq) + H₃O⁺(aq) \(\rightleftharpoons\) HNO₂(aq) + H₂O( \(\ell\) )
• C) NO₂^-(aq) + H₃O⁺(aq) \(\rightleftharpoons\) HNO₂(aq)
• D) H⁺(aq) + OH^-(aq) \(\rightleftharpoons\) H₂O( \(\ell\) )
• E) HNO₂(aq) \(\rightleftharpoons\) NO₂^-(aq) + H₃O⁺(aq)
