Question

The reation between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:

$\begin{matrix} E x p e r i m e n t & [A] m o l L^{- 1} & [B] m o l L^{- 1} & I n i t i a l r a t e m o l L^{- 1} m i n^{- 1} I & 0.1 & 0.1 & 2.0 \times 10^{- 2} I I & - & 0.2 & 4.0 \times 10^{- 2} I I I & 0.4 & 0.4 & - I V & - & 0.2 & 2.0 \times 10^{- 2} \end{matrix}$

Solution

The rate expression
Rate $= k [A]^{1} [B]^{0} = k [A]$
For 1st experiment, $[A] = 0.1 m o l L^{- 1}$
So, Rate $= 2.0 \times 10^{- 2} = k [0.1 m o l L^{- 1}]$
$k = \frac{2.0 \times 10^{- 2} m o l L^{- 1} m i n^{- 1}}{0.1 m o l L^{- 1}} = 0.2 m i n^{- 1}$
For IInd experiment, $4.0 \times 10^{- 2} m o l L^{- 1} m i n^{- 1} = 0.2 m i n^{- 1} [A]$
$[A] = \frac{4.0 \times 10^{- 2} m o l L^{- 1} m i n^{- 1}}{0.2 m i n^{- 1}} = 0.2 m o l L^{- 1} [A] = 0.2 m o l L^{- 1}$
For IIIrd experiment, Rate = k[A]
Rate $= 0.2 m i n^{- 1} \times 0.4 m o l L^{- 1}$
Rate $= 8 \times 10^{- 2} m o l L^{- 1} m i n^{- 1}$
For IVth experiment,
Rate $= k [A]; [A] = \frac{R a t e}{k}$
$[A] = \frac{2.0 \times 10^{- 2} m o l L^{- 1} m i n^{- 1}}{0.2 m i n^{- 1}}$
$= 0.1 m o l L^{- 1}$
$[A] = 0.1 m o l L^{- 1}$
