0.030 M/s
0.005 M/s
please help T_T

Answer 2

this is a very difficult table to understand so i'll help out.\[\left[\begin{matrix}[NH_4^+] [NO_2^-] rate\\ .010M .020M .02M/s \\ .015M .020M .03M/s\\.010M .010M .005M/s\end{matrix}\right]\] Now it's a little easier to see that when the ammonium has increased by a factor of .5 the rate also increases by a factor of .5. This indicates it's 1st order in ammonium.
