question 33

Multiple Choice

• A)K_a = \(\frac{[\mathrm{HA}]}{\left[\mathrm{H}_{3} \mathrm{O}^{+}\right]\left[\mathrm{A}^{-}\right]}\)
• B)K_a = \(\frac { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \left[ \mathrm { A } ^ { - } \right] } { [ \mathrm { HA } ] \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] }\)
• C)K_a = \(\frac { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \left[ \mathrm { A } ^ { - } \right] } { [ \mathrm { HA } ] }\)
• D)K_a = \(\frac { [ \mathrm { HA } ] \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] } { \left[ \mathrm { H } _ { 3 } \mathrm { O } ^ { + } \right] \left[ \mathrm { A } ^ { - } \right] }\)
• E)K_a = \(\frac{\left[\mathrm{A}^{-}\right]}{[\mathrm{HA}]}\)
