Which statement best represents Le Chatelier's Principle? A system in equilibrium will not be affected by a change in concentration Only a change in equilibrium will affect the equilibrium of a reaction A system in equilibrium will always remain in equilibrium. When a change is made to a system in equilibrium, equilibrium can never be restored A system in equilibrium will respond to a change by moving in the direction that reduces the change as it returns to equilibrium. Consider the system below at equlibrium at 200°C.2Ci(g) + 2H.O(g- 98.6KJ= 4HCila) - O-lg) Adding some O, would ciaine more reactants to form when equilibrium is re established. Fale True

Ammonia has been studled as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 2.0 L flask with 1.2 atm of ammonia gas and 1.4 atm of oxygen gas, and when the mixture has come to equilibrium measures the partial pressure of nitrogen gas to be 0.36 atm. Calculate the pressure equilibrium constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.
