[填空题]
The relationship between the concentration of a reactant, A, and the tim:owcky/k9oj4xkj8-q e, f1g,k x4ngft( tio;1 waor a second-order reaction can be expresseg k4ax;t 1 ,inw1(ftgod using the equation below:
$\frac{1}{[A]}$=kt+$\frac{1}{[A{]}_o}$
Where [A] is the concentration of reactant A,$[A{]}_o$,is the initial concentration of reactant A,t is the time in seconds, and k is a constant.

1.Calculate the gradient of the line and state the correct units.
2.Use the graph to determine $[A{]}_o$ (also known as the initial concentration of A)
$[A{]}_o$=  mol dm${}^{-3}$
3.Determine the time at which the concentration of A is equal to an eighth of its initial concentration.
(If you were unable to complete parts (a), and (b), you may use k=0.02, and $A_o$=42)
[A]=  mold m${}^{-3}$;Substitute and rearrange:  seconds
