Using the potential energy diagram below, match each number with the appropriate description. 2 Reaction coordinate Reactants 1. 1 Transition state 1 2. 2 Products 3. 3 Transition state 2 4. 4 Intermediate 5. 5 6. 6 Change in enthalpy (AH) 7. 7 Activation energy 1 8. 8 Activation energy 2 Potential Energy (PE)
Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step. Catalysts decrease reaction rates. Reaction rates increase as concentrations of homogeneous catalysts increase. The fastest step in a reaction is called the rate-determining step. Solid catalysts do not affect reaction rates. As a reaction progresses its rate goes up.
True or false The rate limiting step in a reaction is the slowest step in the reaction sequence.
Reaction rate increases if reactant is added. O True O False
