Question

4NH3 + 5O2 --> 4NO + 6H2O

1. Nitric acid is made by first reacting ammonia and oxygen to form nitric oxide: NH3 (g)+O2 (g)⟶NO(g)+H2O(g)

Calculate the heat of reaction at
a) standard conditions (this is what the book calls ∆ ) and b) at 500 °C. (This is what the book calls ∆ )

2. (Builds off of problem 1). Ammonia gas enters a reactor with 30% more dry air (no water vapor) than is required for complete conversion. These gases enter the reactor at 75 °C and exit at 600 °C. How much heat is required per mole of ammonia fed?
