Which change to a reaction profile would show the reaction is endothermic?
Which of the following is true when a catalyst is used in a reaction?
Which part of a reaction profile represents the minimum energy barrier that must be overcome for reactants to form products?
On a reaction profile, where is the activated complex (transition state) located?
On a reaction profile graph, which vertical distance corresponds to the overall energy change (?H) for the reaction?
Which description of a reversible reaction at dynamic equilibrium is correct?
Which feature of a reaction profile is directly reduced by adding a catalyst?
How does increasing concentration of reactants affect a reaction as illustrated conceptually (not on the profile shape itself)?
When bond energies are: C—H = X, C—C = 347, O=O = 498, C=O = 805, O—H = 464, and the overall reaction energy is -2219 kJ per mole (exothermic), which algebraic procedure finds X?
