Rate law for a reaction is $r=k[A]^2[B]$. If rate constant is $6.25 \ mol^{-2} \ dm^6 \ s^{-1}$,what is the rate of reaction when $[A]=1 \ mol \ dm^{-3}$ and $[B]=0.2 \ mol \ dm^{-3}$?
- A$1.250 \ mol \ dm^{-3} \ s^{-1}$
- B$2.125 \ mol \ dm^{-3} \ s^{-1}$
- C$3.105 \ mol \ dm^{-3} \ s^{-1}$
- D$2.0 \times 10^{-2} \ mol \ dm^{-3} \ s^{-1}$
