CHANGES IN EQUILIBRIUM CONDITIONS - 1
Consider the homogeneous gas-phase reaction,
- 2 SO3 <--> 2 SO2 + O2 DH° = + 198 kJ
The three substances are mixed and the reaction comes to equilibrium.
1. What is the effect of increasing the volume of the container on the equilibrium number of moles of SO2 ? (temperature remaining constant)
- a. increase b. decrease c. no effect
2. What is the effect of injecting O2 on the equilibrium number of moles of SO2 ? (temperature and volume remaining constant)
- a. increase b. decrease c. no effect
3. What is the effect of removing O2 on the equilibrium number of moles of SO3 ?(temperature and volume remaining constant)
- a. increase b. decrease c. no effect
4.What is the effect of injecting an inert gas such as Ne on the equilibrium number of moles of SO2 ? (temperature and volume remaining constant)
- a. increase b. decrease c. no effect
5. What is the effect of decreasing the volume of the container on the equilibrium number of moles of O2 ? (temperature remaining constant)
- a. increase b. decrease c. no effect t
6. What is the effect of increasing the temperature on the equilibrium number of moles of SO2 ? (volume remaining constant)
- a. increase b. decrease c. no effect
7. What is the effect of decreasing the temperature on Kc ? (volume remaining constant)
