Options:
  • A Rate of formation of $C$ is twice the rate of disappearance of $A$
  • B $t_{1 / 2}$ is a constant
  • C Unit of $k$ must be $s^{-1}$

The correct answer is: Value of $k$ is independent of the initial concentrations of $A$ and $B$
For $2 A+B \rightarrow C$
Rate $=K[A][B]$
Value of rate constant $K=A e^{-E_a / R T}$ here $K$ is independent of the initial concentration of $A$ and $B$.
