MCQ
From the following which is a second order reaction
  • A
    $K = 5.47 \times {10^{ - 4}}\,{\sec ^{ - 1}}$
  • B
    $K = 3.9 \times {10^{ - 3}}\,{\rm{mole}}\,\,{\rm{lit}}\,\,{\sec ^{ - 1}}$
  • $K = 3.94 \times {10^{ - 4}}\,{\rm{lit}}\,\,{\rm{mol}}{{\rm{e}}^{{\rm{ - 1}}}}\,\,{\sec ^{ - 1}}$
  • D
    $K = 3.98 \times {10^{ - 5}}{\rm{lit}}\,\,{\rm{mol}}{{\rm{e}}^{{\rm{ - 2}}}}\,\,{\sec ^{ - 1}}$

Answer

Correct option: C.
$K = 3.94 \times {10^{ - 4}}\,{\rm{lit}}\,\,{\rm{mol}}{{\rm{e}}^{{\rm{ - 1}}}}\,\,{\sec ^{ - 1}}$
