The reaction of NO2 with ozone produces NO3 in a second-order reaction overall.
NO2(g) + O3(g) --> NO3 (g) + O2 (g)
If the rate constant for the reaction is 1.69 x 10^-4 M-1s-1 at 298 K. What is the rate of the reaction when [NO2] = 1.77 x 10^-8 M and [O3] = 1.59 x 10-7 M?
M/s

What is the rate of the appearance of NO3 under these conditions?
M/s

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
