Lecture 7

Question 1

What to do in equilibrium constant problems

Answer 1

1. Find K/Kp and Q to see if reaction will proceed to the right or left (to get either -x or +x)
2. ICE table

Question 2

What is Le Chatelier’s Principle

Answer 2

System will adjust to negate perturbation
–> if change is imposed on system at equilibrium, the position of eq will shift in the direction that tends to reduce change

Question 3

Ways to change pressure that affect equilibrium

Answer 3

1. Add/remove gaseous R or P
2. Change volume of container
   –> system will respond by reducing its moles of gaseous molecules

Question 4

How changing temperature affects equilibrium

Answer 4

1. Change in T affect equilibrium constant K
2. Adding energy will make the system respond by removing that energy
