Question
According to Le Chatelier's Principle, what happens to the position of equilibrium when the pressure is increased in a gaseous reaction with unequal numbers of moles of gas on either side?
Answer
Increasingthe pressure will shift the equilibrium towards the side with fewer molecules of gas.
Explanation
This answer demonstrates an understandingof Le chatelier's Principle and its application to changes in pressure. The question tests the student's ability to predict the effect of pressure changes on equilibrium positions in gaseous reactions.
Common mistake
Misunderstanding Pressure Effects
Students often think that increasing pressure will always increase the rate of reaction rather than shifting the equilibrium position.
Remember that increasing pressure shifts the equilibrium towards the side with fewer gas molecules, which may not necessarily increase the reaction rate.
