[填空题]
The relationship between vkkcb.*s9q tx12n g;rthe concentration of a reactasfc2q/cj.da7mw/ cj7iq l2*rnt, A, and the time, for a sw2c*q/7ajfl27.msi jq rd/ ccecond-order reaction can be expressed using the equation below:
$\frac{1}{[A]}$=kt+$\frac{1}{[A]_0}$
Where [A] is the concentration of reactant A,[A] is the initial concentration of reactant $[A]_0$,t is the time in seconds,and k is a constant.
1.Calculate the gradient of the line and state the correct units.The number=
2.Use the graph to determine $[A]_0$(also known as the initial concentration of A).
$[A]_0$= mol dm$^{-3}$
3.Determine the time at which the concentration of A is equal to an eighth of its initial concentration.
[A]= mol m$^{-3}$
(If you were unable to complete parts (a), and (b), you may use k=0.02, and $[A]_0$ =42).
