√r0=4[A0], r0=16[A0]2, Rate =k[A0]n ∴ k=16 and n=2

Q. The kinetic study of a reaction like vA $\to$ P at 300 K provides the following curve, where concentration is taken in mol dm $^{-} 3$ and time in min.
Identify the correct order(n) and rate constant(k) :

n = 0, k = 4.0 mol dm $^{- 3} mi n^{- 1}$

n = 1/2, k = 2.0 $m o l^{1/2}$ $d m^{3/2} mi n^{- 1}$

n = 1, k = 8.0 $mi n^{- 1}$

n = 2, k = 16.0 $d m^{3} m o l^{- 1} mi n^{- 1}$

$r_{0} = 4 [A_{0}], r_{0} = 16 [A_{0}]^{2}, R a t e = k [A_{0}]^{n} ∴ k = 16 an d n = 2$

Q. The kinetic study of a reaction like vA → P at 300 K provides the following curve, where concentration is taken in mol dm−3 and time in min. Identify the correct order(n) and rate constant(k) :

n = 0, k = 4.0 mol dm −3min−1

n = 1/2, k = 2.0 mol1/2 dm3/2min−1

n = 1, k = 8.0 min−1

n = 2, k = 16.0 dm3mol−1min−1
