Question 8 (0.5 points)

Consider the following reaction coordinate diagram.

Based on this diagram, which of the following is correct?

Question 8 options:

3 represents heat of reaction and the reaction is endothermic

5 represents heat of reaction and the reaction is exothermic

3 represents heat of reaction and the reaction is exothermic

2 represents heat of reaction and the reaction is exothermic.

2 represents heat of reaction and the reaction is endothermic

1 and 5

2 and 4

All will change their energy value.

1, 3, and 5

2, 3, and 4

Explanation / Answer

5)

Catalyst decreases the activation energy

So, the peak energy comes down

This will effect 2 to decrease and 4 to decrease

Answer: 2 and 4

6)

transition state is at the peak

Answer: 4

7)

equilibrium constant doesn’t depend on concentration.

It depends only on temperature

Answer: False

8)

heat of reaction = energy of product - energy of reactant

This is given 3 and it is negative

So, it is exothermic

Answer: 3 represents heat of reaction and the reaction is exothermic
