Part A For a certain reaction, Kc = 9.58Ã104 and kf= 0.564 Mâ2â sâ1 . Calculate the value of the reverse rate constant, kr, given that the reverse reaction is of the same molecularity as the forward reaction. Express your answer with the appropriate units. Include explicit multiplication within units, for example to enter Mâ2â sâ1 include â (multiplication dot) between each measurement. kr =
Part B For a different reaction, Kc = 73.6, kf=513sâ1, and kr= 6.97 sâ1 . Adding a catalyst increases the forward rate constant to 3.85Ã104 sâ1 . What is the new value of the reverse reaction constant, kr, after adding catalyst? Express your answer with the appropriate units. Include explicit multiplication within units, for example to enter Mâ2â sâ1 include â (multiplication dot) between each measurement. kr =
Part C Yet another reaction has an equilibrium constant Kc=4.32Ã105 at 25 âC. It is an exothermic reaction, giving off quite a bit of heat while the reaction proceeds. If the temperature is raised to 200 âC , what will happen to the equilibrium constant?
