For the gas phase decomposition of nitrogen dioxide at ( 383^{circ} mathrm{C} ) [ 2 mathrm{NO}_{2} longrightarrow 2 mathrm{NO}+mathrm{O}_{2} ] the following data have been obtained: egin{tabular}{|l|l|l|l|l|} hline( left[mathrm{NO}_{2} ight], mathrm{M} ) & ( mathbf{0 . 3 5 0} ) & 0.199 & 0.139 & 0.103 \ hline time, ( mathrm{s} ) & 0 & 4.00 & 8.00 & 12.00 \ hline end{tabular} What is the average rate of disappearance of ( mathbf{N O}_{2} ) over the time period from ( t=mathbf{4 . 0 0} mathbf{s} ) to ( t=mathbf{8 . 0 0} mathbf{s} ) ? ( mathrm{M} mathrm{s}^{-1} )
