The details
You may read online that chocolate helps a rat with breathing problems. It doesn't — a rat struggling to breathe needs a vet. The RSPCA lists sneezing, wheezing and breathing strangely among the signs to call a vet about.
What to do if your rat ate it
Call a vet straight away — ideally one who treats exotic pets — and don't wait for symptoms. Rats can't vomit, and the RSPCA warns that even a small amount of something harmful can kill them. Tell the vet what your rat ate, roughly how much and when, and bring the packaging if there is one. Don't try home remedies or human medicines: the RSPCA warns these are very dangerous to rats.
