Not all powers revealed, why???

Ok, so anyone here most likely knows Superman's abilities like their abc's. So when Batman used both the smoke(x-ray vision should have seen through) AND the Krypto-Gas, he should have been able to BLOW IT AWAY with his super breath? Right? If not actually freeze the gas particles, idk I'm not a chemist. But throughout the entire film, which I did thoroughly enjoy, did he EVER tap this skill. I suppose when the writers were coming up with something that Batman would be able to use they were forced to omit the fact that he could have stopped those weapons.
Don't get me wrong, the fight scene was integral to the movie, and a good one at that. But there was just that itch that never got scratched and drove me nuts.
