What is the overall reaction order for a reaction with the following rate law? Rate =
k[BrO 3 ][Br][ht]2

4

Explanation:

In a rate law, The reaction order is basically the superscript (power) of the concentration of the reaction. It defines the extent to which the rate of the reaction depends on the concentration of the reaction.

In this rate law, the order of the reactants are;

[BrO3] = 1

[Br] = 1

[ht] = 2

The overall reaction order is the sum total of the individual orders. We have;

1 +1 + 2 = 4

  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-

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
