4) The initial rate of the reaction between substances P and Q was measured in a series of
experiments and the following rate equation was deduced.
rate = k[P]?[Q]
Complete the table of data below for the reaction between P and Q

![rate = k[P]^{2} [Q]](/tpl/images/1366/6277/fe327.png)
![rate= k[P]^{2} [Q]\\=[Q]=\frac{rate}{k.[P]^{2} } \\and \\\\\\\ [P]=\sqrt{\frac{rate}{k.[Q]} }](/tpl/images/1366/6277/446ad.png)
![k=\frac{rate}{[P]^{2}[Q] } \\ =\frac{4.8*10^-3}{(0.2)^{2} 2. (0.30)} \\ =0.4](/tpl/images/1366/6277/9a08a.png)
![[Q]=\frac{rate}{k.[P]^{2} } \\ =9.6*10^-3 / (0.4 *(0.40)^{2} \\ =0.15mol.dm^{-3}](/tpl/images/1366/6277/65e00.png)
![[P]=\sqrt{\frac{rate}{k.[Q]} }\\=[P]=\sqrt{\frac{19.2*10^-3}{0.60*0.4} } \\=[P]=0.283mol.dm^{-3}](/tpl/images/1366/6277/1779c.png)
