K

For example, if the chemical reaction has the following formula :

A+2B->C+3D

Then K

(Where [ A ] means the molarity of the compound A)

This is what they are teaching us at least, but i find it not really logical, for may reasons, here is one.

suppose we multiply the whole formula by 2

2A+4B-->2C+6D

(the equation was edited after the notice of Mike)

The value of K

Anyone can explain what is happening please ?

Thanks in advance

_{c}is the constant of equilibrum for a certain chemical reaction.For example, if the chemical reaction has the following formula :

A+2B->C+3D

Then K

_{c}=([ C ].[ D ]^{3})/([ A ].[ B ]^{2})(Where [ A ] means the molarity of the compound A)

This is what they are teaching us at least, but i find it not really logical, for may reasons, here is one.

_{c}will get squared, but this seems wrong since both fomulas are for the same reaction !Anyone can explain what is happening please ?

Thanks in advance
