Answer to Question #76176 in Physical Chemistry for Michael

Question

The reaction below is exothermic:
2SO2 (g) + O2 (g) ⇌ 2SO3 (g)

Le Chatelier's Principle predicts that ________ will result in an increase in the number of moles of SO3 (g) in the reaction container.

A) removing some oxygen
B) increasing the temperature
C) decreasing the pressure
D) increasing the pressure
E) increasing the volume of the container

Answer 1

P*V/T = const;
So increasing the pressure will result in an increase in the number of moles of SO3 (g) in the
reaction container.
D) increasing the pressure.
Answer: D) increasing the pressure.
