Students have asked these similar questions

A. For a certain reaction, Kc = 4.48×106 and kf= 4.10×10−2 M−2⋅s-1 . 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 M−2⋅s−1nclude ⋅⋅ (multiplication dot) between each measurement. B. For a different reaction, Kc = 97.7, kf=3.00×10^3s−1 and kf=3.00×10^3s−1 , and kr= 30.7 s−1. Adding a catalyst increases the forward rate constant to 1.37×106 s−1s−1 . 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 M−2⋅s−1 include ⋅ (multiplication dot) between each measurement.

Consider the reaction N₂O(g) →N₂(g)1/2O₂(g) with Au has catalyst (a) Is the gold a homogeneous or a heterogeneous catalyst?(b) On the same set of axes, sketch the reaction energy dia-grams for the catalyzed and the uncatalyzed reaction

Bromine, Br2, reacts with chlorine, Cl2, in a tetrachloromethane, CCI4, solution to form bromine monochloride, BrCI. At equilibrium, the concentrations of Br2, Cl2, and BrCI in a reaction mixture were found to be 0.048 mol dm-3, 0.037 mol dm-3, and 0.111 mol dm-3, respectively, at 298 K. Calculate the equilibrium constant in terms of concentration, Kc, at this temperature.
