What exactly are constants? Are they just used to make the equation work or is there something more meaningful than this? Right now I am studying rate of reactions and they go something like this:(adsbygoogle = window.adsbygoogle || []).push({});

rate = k [A]^x^y

It seems like k is only there to make the equation work. It would seem like k is the responsiveness of rate to concentration. But this becomes meaningless when comparing two reaction of different orders; they take on different units for different orders.
