Nitric acid is produced commercially by the Ostwald process. In the first step ammonia is oxidized to nitric oxide: 4NH3(g) +502 (9)→ 4NO(g) + 6H₂O(g) Assume this reaction is carried out in the apparatus diagramed below. 3.00 L NH3 0.500 atm 100 1.50 L 0₂ 1.50 atm The stopcock between the two reaction containers is opened, and the reaction proceeds using proper catalysts. Calculate the partial pressure of NO after the reaction is complete. Assume 100% yield for the reaction, assume the final container volume is 4.50 L, and assume the temperature is constant. Partial pressure of NO = atm

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.
