Question

For the following data for the zero order reaction $A\to$ products. Calculate the value of k.
Time [A]
0.0 0.10 M
1.0 0.09 M
2.0 0.08 M

• A. $k=0.01Mmi{n}^{-1}$
• B. $k=0.03Mmi{n}^{-1}$
• C. $k=0.06Mmi{n}^{-1}$
• D. $k=0.08Mmi{n}^{-1}$

Answer 1

The correct option is A $k=0.01Mmi{n}^{-1}$

For zero order reaction:
$rate=k$

$k=(0.10-0.09)/1=0.01/1=0.01Mmi{n}^{-1}$

$Rate=\frac{0.09-0.08}{2-1}=0.01Mmi{n}^{-1}$
