Question
Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since
its reaction with oxygen produces only nitrogen and water vapor. The following reaction takes
place (at a certain temperature) as follows:
4 NH,(g) + 302(g)
- 2 N2(g) + 6 H,O(g)
2.1
In the reaction above, identify which reactant is oxidized and which is reduced
NH,
O2
2.2
An industrial chemist studying this reaction fills a 500. mL flask with 1.3 atm of ammonia
gas and 1.2 atm of oxygen gas, and when the mixture has come to equilibrium measures the
partial pressure of nitrogen gas to be 0.33 atm. Calculate the pressure equilibrium constant
for this reaction. You must fill out the ICEE table below for full credit. Round your answer to 2
significant digits. Make sure to box your final answer for K,. If you need more space to show
