What kind of reaction is represented by #2K + I_2 -> 2KI#?

Answer 1

Serenity Allen

#"A redox reaction..........."#

And redox reactions are conceived to occur on the basis of FORMAL electron transfer:

Potassium metal is oxidized to potassium ion....

#K(s) rarr K^(+) + e^(-)# #(i)#

And iodine is reduced to iodide ion......

#1/2I_2+e^(-) rarr I^-# #(ii)#

And we add #(i)# and #(ii)# together to eliminate the electrons........

#K+ 1/2I_2 rarr KI#............

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
