How does the rate of reaction change if a first order reactant's concentration increases?
Increases by the same factor eg.
Increases by 2
: Rate increases by 2
^{1 }
^{}
How does the rate of reaction change if a second order reactants's concentration changes?
Increases by that factor to the power 2
eg.
Increases by 2 :
Rate increases by 2
^{2 }
= 4
Increases by 0.5 :
Rate increases by 0.5
^{2 }
= 0.25

What is the electron configuration of
Chromium?

^{1 }
3d
^{5}
^{}
Chromium has one electron in each orbital of the 3d subshell rather than 2 in the 4s subshell.
This gives it more stability.
