# Chemical equilibrium

## Main Question or Discussion Point

H2+1/2 O2 ---------> H20

If the equation is multiplied by 2
Will the equilibrium constant change or remain constant ???

The square of a constant is still a constant.

Sorry, I don't understand, can you clarify what you mean, thanks.

Equilibrium constant will change, but as it will describe different reaction equation, you will find when the correct combination of the equation and constant is used, results of equilibrium calculations are identical.

Suppose you calculate a constant for the above reaction and its value is K. If you multiply the equation by 2, then the new constant will be K2 .

But this should not matter for any intensive or molar quantity.
