  • Chem II help?

    Your answer: 
    A reaction, A(aq)+B(aq) <---> C(aq) has a standard free-energy change of –5.45 kJ/mol at 25 °C. What are the concentrations of A, B, and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively? Also can you do the same problem but with -3.78 kJ/mol at 25 °C instead of the -5.45... show more

  • What is the Gibbs free energy of the reaction?

    Your answer: 
    The osmotic pressure was measured at the beginning of the reaction and after the equilibrium has been reached at T=27 C. The osmotic pressures are at initial = 0.049 atm and at equilibrium = 0.060 atm. What is the Gibbs free energy of the reaction if the total concentration of the products is 100 times greater than the concentration of the reactant
