i dont have any references to the atm needed for the reaction. do you have any suggestions?

thats what i thought, if there no references to it then it would probably be carried out at atm.

No, one of the requirements IS one atm. If your write that in the exam you get one mark.
Obviously one atm is 100KPa which is the atm pressure under normal conditions.
