Practice 1: Equilibrium Calculations
Work
1. Review the equilibrium calculations covered in Lessons 2 to 5.
2. Do questions 2, 3, 5, 6, 7, 8 on page 459.
Hints
Question 3: You must solve a quadratic to find x in question 3 (use the quadratic formula).
Question 5: Find the equilibrium concentrations, then calculate K (two steps).
Question 8: Notice the very small K-value.
3. Check your solutions and review as necessary.
