Lab 2B – The Equilibrium Constant
1) How is the equilibrium constant calculated? (1 pt)
2) When a reaction reaches equilibrium, if there is more product than reactant, what happens to the K value? (1 pt)
3) When a reaction reaches equilibrium, if there is more reactant than product, what happens to the K value? (1 pt)
4) The formation of COCl2 has an equilibrium constant of 4.57×109 at 25oC. What happens to the K value when temperature is increased to 200oC? (1 pt)
5) The formation of NO has an equilibrium constant of 1.0×10–30 at 25oC. What happens to the K value when temperature is increased? (1 pt)
Lab 2B – The Equilibrium Constant Answer
- Equilibrium Constant can be calculated by doing the following: Write the reaction’s equilibrium constant expression. To solve for x, substitute the known K value and the final concentrations. Calculate each substance’s final concentration in the reaction mixture. Substituting these values into the equilibrium constant expression to get K will help you double-check your answers.
