Constant Pressure

Under what circumstances should you assume there is a constant pressure?

Constant pressure can be assumed if a pressure is given and nothing in the problem says that it changes. It can also be assumed if the problem says that the reaction or system takes place at standard conditions, which would mean that they take place at 1 atm.

Also, constant pressure can be assumed if you are dealing with an open system.

If they use the term "isobaric" in the problem it means that the pressure is staying constant
