I m trying to write a Free Energy equation for the electrolysis of water and I cant figure out how to get an arrow into my equation. I know the \arrow thing but i don't know where to put it. If you could help that would be much appreciated.

My equation right now is.
$\triangle{G}$ $2H_2O \arrow 2H_2+O_2$

I think I am putting the \arrow in the wrong place. I am totally new to this so any help is appreciated.

When i do $\triangle{G}$ $2H_2O > 2H_2+O_2$ it works but I really want the arrow.

Thanks

Check out this thread on PhysicsForums.com. There are a ton of great examples of LaTeX, including limits, integrals, summation notation, and more.
