Ethylene oxide is produced from the reaction of ethylene and oxygen at 270-290°C and 8-20 atm. In order to prevent potentially dangerous pressure buildups, the container in which this reaction takes place has a safety valve set to release gas when the pressure reaches 25 atm. If a 75-m3 reaction vessel contains 3.5 ✕ 104 moles of gas, at what temperature will the pressure reach 25 atm? (There are 103 L per m3.)

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
