Chapter 16: Q16.63P (page 731)

For the reaction $A_{2} + B_{2} 鈫� 2 A B$ , $E_{a (f w d)} = 125 k J / m o l$ and $E_{a (r e v)} = 85 k J / m o l$ . Assuming the reaction occurs in one step,
(a) Draw a reaction energy diagram;
(b) Calculate role="math" localid="1663350265727" $鈭� {H^{0}}_{r 脳 n}$ ; and
(c) Sketch a possible transition state.

(a) A reaction energy diagram is

Reaction Energy Diagram

(b) the $鈭� {H^{0}}_{r 脳 n}$ is equal to 40 kJ/mol.

(c) A transition represents the weakening of old bonds (A-A) and (B-B) along with the formation of new bonds (A-B). Draw the transition state for the reaction:

Step by step solution

Step 1: Draw a reaction energy diagram

Since the reaction is endothermic, the products鈥� energy will be higher than that of the reactants. Draw the reaction's energy diagram:

Step 2: Calculate ∆H0r×n

Determine the $鈭� {H^{0}}_{r 脳 n}$ as follows:

$鈭� {H^{0}}_{r 脳 n} = E_{a (f w d)} - E_{a (r e v)} = 125 k J / m o l - 85 k J / m o l = 40 k J / m o l$

Thus, it $鈭� {H^{0}}_{r 脳 n}$ is equal to 40 kJ/mol.

Step 3: Sketch a possible transition state

A transition represents the weakening of old bonds (A-A) and (B-B) along with the formation of a new bond (A-B). Draw the transition state for the reaction:
