The AG is the free energy change of a reaction- at its initial stage. when the concentration of all reactants and products are set to be 1M at 0°C. when the concentration of reactants and products are at their actual prevalent concentrations in living cells. under standard conditions. at its equilibrium. Consider this equilibrium: CH3-COOH + H₂O CH3-COO + H3O+ Which of the following statements most accurately describes what occurs when the pH is increased? A new equilibrium is established that favors the products. A new equilibrium is established that favors the reactants. The equilibrium constant Keq increases. The position of the equilibrium remains the same. The equilibrium constant Keq decreases.
When the temperature-time data graph was reviewed, it was found that an error had been made in determining ΔT. Instead of 4.76 °C, ΔT was actually 4.70 °C. Based on this change only, calculate the correct ΔH neutralization for the reaction of NH3, and acetic acid.
