O The molecules can only collide at the interface between the phases, giving little reaction. O The molecules of the reactants are not able to mix completely in the two phases. The presence of twdwphases causes the reactants to react in different ways. O The molecules in one phase have no contact with the molecules in the other phase. Why do we expect the reaction of two solids or two solids dissolved in immiscible liquids to be slow? QUESTION 5

Ammonla has been studied 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 partlal pressure of nitrogen gas to be 0.36 atm. Calculate the pressure equilibrlum constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.
