For the reaction given below, the standard change in free energy has a positive value. A+B<-->C+D Changing the conditions of the reaction can alter the value of the change in free energy (?G). Sort the following conditions as to whether each would decrease the free energy value, increase the free energy value, or not change the free energy value for the reaction. For each change, assume that the other variables are kept constant. a. Adding a catalyst decrease the free...

Changing the conditions of the reaction can alter the value of ΔG. => Choose TRUE or FALSE for the following statement: Increasing [C] and [D] will decrease ΔG Pyruvic acid has a pKa of 2.5. Its conjugate base is pyruvate. Which form, the acid or the base, dominates at pH 7.4? neither Pyruvate Pyruvic acid Both For the...
er at initial change (AG The standard free energy change (AG) for ATP hydrolysis is -30.5 kJ/ mol ATP, ADP, and I are mixed together at initial concentrations of 1 M each then left alone until the reaction below has come to equilibrium. For each species (ie. ATP. ADP and P.) indicate whether the concentration will be equal to 1 M, less than 1 M, or greater than 1 M after the reaction had reached equilibrium. Explain why. ATP +...

If you find that the standard Gibbs free energy change for a reaction is -6.56 kJ/molk, what is the equilibrium constant for the reaction at 25.0 °C? Be careful with your units in the calculation. For a reaction, a plot of In K versus inverse temperature is found to be linear and fits the following equation: y = -1,838x + 6.81. What is the value of AH? Give your answer with units of kJ/molk; however, you should not type in...
