7. Reactions A and B were studied and found to produce the given energy diagrams. 150 150 Energy 100 (kJ/mol) 100 Energy (kJ/mol) 50 50 Reaction progress Reaction progress Reaction A Reaction B A third reaction, C was studied with a measured activation energy of 55 KJ/mol. Assume all reactions take place at the same temperature. Reaction A is slowest a. b. Reaction B is slowest c. Reaction C is slowest d. All reactions happen at the same rate.

A. Draw a reaction coordinate diagram that is consistent with the shown chemical equations and observations. Clearly label reactants, products, intermediates, activation energy (Ea), and transition states. SM Int P Both steps are exergonic. SM - Int is the slowest step. B. Draw a reaction coordinate diagram that is consistent with the shown chemical equilibrium and observations. Clearly label reactants, products, and transition states.

Consider the following reaction coordinate diagram. Energy (kJ) 50 45 40 30 20 15 10 5 0 Extent of reaction (a) Which is the rate-limiting step in this reaction?

what is the best method to investigate rate of reaction in a practical

Energy (kJ/mol) Select the most appropriate reaction coordinate diagram for this reaction from the graphs shown below: Energy (kJ/mol) 10 a Ob C d 15 20 A Energy (kJ/mol) 25 B 20 15 10 0 0 Reaction Coordinate Reaction Coordinate 25 20 C 15 16 14 10 Energy (kJ/mol) D 12 10 0 Reaction Coordinate Reaction Coordinate The reason that this graph is the best choice is the highest rate constant goes with the second step and the reaction is exothermic the highest rate constant goes with the first step and the reaction is endothermic the highest rate constant goes with the first step and the reaction is exothermic the highest rate constant goes with the second step and the reaction is endothermic In order to speed up the reaction, the team should decrease the temperature of the soap solution increase the temperature of the soap solution keep the temperature of the soap solution the same because the reaction is endothermic the reaction is exothermic the hydrogen peroxide molecules will have…

Consider the following hypothetical reaction coordinate diagram with stages represented by I, II, and III, and choose the true statement about the steps in the forward and reverse mechanisms. Which is a TRUE statement? a) Step II --> III is faster and less energetically favorable than step II -->I b) Step II --> III is faster and more energetically favorable than step II -->I c) Step II --> III is slower and less energetically favorable than step II -->I --> Ill is slower and more energetically favorable than | || ||| d) Step II step II -->I
