Question 1
Consider the reaction where the equilibrium constant K = 0.002 and the initial concentration of A is 0.050 M. Apply the Approximation Method and verify if the approximation is valid. What are the values at equilibrium?
π‘ Hint: Review how K interacts with concentration in a reversible environment.
Question 2
If K = 0.1 and the initial concentration is 0.200 M, analyze if the Approximation Method applies and solve for x accordingly.
π‘ Hint: Think carefully about the ratio of x to initial concentration when close to 5%.
