iPad 2:59 PM * 55% - . Chapter 14 Homework Set D: Attempt1 Question Completion Status Below is a potential energy diagram for a reaction with a 2-step mechanism Step 1 X+ W >Y + V (slow step) Step 2 Y+W- ->X+ Z Energy Diagram for 1,2- verus 1,4- additions to butadiene nigher energy ower energy) Energy 1 2 produet 1,4 product Which letter (A, B, C, D, or E) on the potentia' energy diagram represents the point at which the transition state for the first step is fully formed? A and B Which letter (A, B, C, D, or E) on the potential energy diagram represents the point at which the transition state for the second step is fully formed? Which letter (A, B, C, D, or E) on the potential energy diagram represents the point at which the reaction intermediate is fully formed?Explanation / Answer
B
D
C
Y(reaction intermediate form and consume during reaction)
X (Catalyst is not consumed in reaction)
2W ---V+Z
A &B (the energy difference between reactant and ist transition state is called activation energy
Exothemic (product is below reactant so exothemic)
