The rate equation for the reaction $2A + B \to C$ is found to be: $\text{rate} = k[A][B]$. The correct statement in relation to this reaction is that the
- ARate of formation of $C$ is twice the rate of disappearance of $A$
- B$t_{1/2}$ is a constant
- CUnit of $k$ must be $s^{-1}$
- DValue of $k$ is independent of the initial concentrations of $A$ and $B$
