Chapter 6: Q21E (page 181)

Draw an energy diagram for a two-step reaction withKeq > 1. Label the overall 螖骋o, transition states, and intermediate. Is螖骋o positive or negative?

Short Answer

Expert verified

螖骋oForthereactionisnegative

Step by step solution

01

Energy profile diagram

An energy profile diagram is a plot of energy against the reaction coordinate. This shows when the reaction proceeds how the energy of the reactant and product changes.

02

Step 2: Relation between Keq and exergonic reaction

WhenKeq greater than 1 then the energy is out in the reaction which means the reaction is exergonic.

When Keqless than 1 is then the energy is in the reaction which means the reaction is endergonic.

If Keq> 1 then螖骋o is negative.

03

Energy profile diagram showing Keq> 1

If Keq> 1 then 螖骋ois negative as shown in the following diagram.
