When writing a rate law for a reaction mechanism with an equilibrium preceding the rate-determining step, the rate law will have to be constructed by using data about the: Select the correct answer below: rate constant for the rate-determining step rate constant for the reverse reaction of the equilibrium concentration of the product of the equilibrium all of the above

All of the above are very much valid

Explanation:

The two key steps in determining rate law are as follows;

1. The sum of each elementary step in a reaction mechanism must yield the overall reaction equation.

2. The rate law of the rate-determining step must agree with the experimentally found rate law.

So therefore, determination of rate constant for rate determining step, rate constant for the reverse reaction and concentration on the product of the equilibrium are all under these two major keys.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

  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-
