For a zero order reaction,$A \longrightarrow \text{product}$,the concentration of $A$ decreases from $1.2 \ mol \ dm^{-3}$ to $0.4 \ mol \ dm^{-3}$ in $240 \ s$. What is the rate constant of the reaction?
- A$0.1 \ mol \ dm^{-3} \ min^{-1}$
- B$0.2 \ mol \ dm^{-3} \ min^{-1}$
- C$0.3 \ mol \ dm^{-3} \ min^{-1}$
- D$0.4 \ mol \ dm^{-3} \ min^{-1}$
