The rate law for the reaction $A + B \rightarrow \text{product}$ is given by $\text{rate} = k[A][B]$. Calculate $[A]$ if the rate of reaction and rate constant are $0.25 \ mol \ dm^{-3} \ s^{-1}$ and $6.25 \ mol^{-1} \ dm^3 \ s^{-1}$ respectively,and $[B] = 0.25 \ mol \ dm^{-3}$.
- A$0.22 \ mol \ dm^{-3}$
- B$0.16 \ mol \ dm^{-3}$
- C$0.30 \ mol \ dm^{-3}$
- D$0.25 \ mol \ dm^{-3}$
