Chemical Equilibrium with Constant Values Questions
- For the chemical reaction A ⇌ B, the equilibrium constant Keq = 0.02 at 25°C. For the chemical reaction B ⇌ C, the equilibrium constant at 25°C is Keq = 1000
- Determine the standard state Gibbs free energy (ΔG°’) for both these reactions. (Hint: note that the temperature is 25°C, which is 298.15 K)
- Determine the equilibrium constant Keq and standard state Gibbs free energy (ΔG°’) for the chemical reaction A ⇌ C
- The reaction pyruvate + ATP ⇌ ADP + PEP is catalyzed by the enzyme pyruvate kinase. ΔG°’ for this reaction is +31.4 kJ/mol.
- Does this reaction move forward (from left to right) or backward under conditions of the standard state? What is meant by “standard state conditions” anyway?
- Calculate the equilibrium constant (Keq) for this reaction at 25°C.
- The concentrations of reactants and products of this reaction are measured in a particular cell at 37°C and found to be: pyruvate (24.9 mM); ATP (12.5 mM); ADP (0.14 mM); and PEP (0.01 mM). Calculate the Gibbs free energy for this reaction under these conditions.
- Will the reaction proceed spontaneously in the forward direction in this cell? Why or why not?
- Imagine that you have 500 mL of pure water. In other words, there is nothing in your beaker except for H2O molecules.
- What would be the pH of this water after it is allowed to reach equilibrium with the products of its spontaneous ionization H+ and OH–?
- What would be the pH of the solution that resulted from dissolving 0.004 moles of NaOH in the water?
