$A_{(g)} + 2B_{(g)} \to$ product is an elementary reaction. Which of the following is incorrect?

  • A
    $\frac{-d[A]}{dt} = K[A][B]^2$
  • B
    If $[B]$ is taken in excess,$t_{1/2}$ does not depend on the concentration of $A$ and $B$.
  • C
    If $[B]$ is in excess,it is a Pseudo first-order reaction.
  • D
    If $[A]$ is in excess,it is a Pseudo second-order reaction.
