(a)
Interpretation:
The slowest step in the given mechanism has to be identified.
Concept Introduction:
When the rate constants for each of the steps in the mechanism are given, we can identify the slowest or the rate determining step. Lower the value of rate constant, slower will be the reaction.
(b)
Interpretation:
The step with the lowest activation energy has to be identified.
Concept Introduction:
For a reaction to take place, the reactants must cross the minimum energy barrier called the activation energy. So, for a reaction with lower activation energy, the reactants can easily convert to products as the energy barrier is less. So, lower activation energy, greater will be the rate constant or the reaction rate.

- 7-45 (Chemical Connections 7C) A painkiller—for example, Tylenol—can be purchased in two forms, each containing the same amount of drug. One form is a solid coated pill, and the other is a capsule that contains tiny beads and has the same coat. Which medication will act faster? Explain.arrow_forwardIn general, can we predict the effect of doubling the concentration of A on the rate of the overall reaction A+BC? Can we predict the effect if the reaction is known to be an elementary reaction?arrow_forward7-29 The following reaction was allowed to reach equilibrium at 25°C. Under each component is its equilibrium concentration. Calculate the equilibrium constant, K, for this reaction.arrow_forward
