For following data for hydrolysis of benzene diazonium chloride $C_6H_5-N=N-Cl+H_2O\rightarrow C_6H_5OH+HCl+N_2(g)$, What is the first order calculate rate constant?

Question

Time(min)	0	2	8	16	24	50	$\infty$
Pressure(P) of $N_2$ at constant volume	0	1.6	6.2	11.2	15.5	24.4	34

 

$\begin{array}{1 1}(a)\;3.8\times 10^{-2}min^{-1}\\(b)\;2.62\times 10^{-2}min^{-1}\\(c)\;3.4\times 10^{-2}min^{-1}\\(d)\;2.49\times 10^{-2}min^{-1}\end{array}$
