Why does an increased temperature cause a reaction to occur slower? A. It does not. The increased temperature causes the reaction to occur more quickly
B. The increased temperature makes the molecules more resistant to sucessful collision, they bounce off of each other sentiam
C. The increased kinetic energy causes the particles to move faster, causing more collisions.
D. The increased potential energy in the particles means more energy is needed from the environment for the activation energy Post Selection

  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-

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
