$A$ substance $A$ decomposes by a first order reaction starting initially with $[A]_0 = 2.00 \, M$ and after $200 \, \min$,$[A]_t = 0.15 \, M$. For this reaction,what is the value of the rate constant $k$?
- A$1.29 \times 10^{-2} \, \min^{-1}$
- B$2.29 \times 10^{-2} \, \min^{-1}$
- C$3.29 \times 10^{-2} \, \min^{-1}$
- D$4.40 \times 10^{-2} \, \min^{-1}$
