4NH3+5O2->4NO+6H2O a)what are the oxidation numbers for NH3 and NO? What is the reducing agent in this reaction b) when 8 moles of NH3 are combined with 10 moles of O2 in a rigid container the initial pressure before a reaction occurs is 3.2 atm. What will be the pressure inside the container after the reaction occurs if the temperature remains constant (above the boiling temperature of water)? Assume 100% yield. c) The container from part b is cooled 5 C causing all the water vapor to condense to a liquid- the other gases remain gases. The mass of the liquid is 212 g. What is the true % yield of the reaction? d) The total pressure of the container after the water condenses (5C) is .857 atm. What are the partial pressures of the 4 gases at 5C. e)What was the temperature of the container in Kelvin before it was cooled to 5C?
