Energy Diagrams Practice Problems

What is the minimum energy required for a chemical reaction to occur?

Show the energy diagram for an exothermic reaction and label it with Energy, Reaction progression, Reactants, Products, and ΔH.

Determine and explain which of the following reactions is more rapid: reaction A with E_act = 10.5 kJ/mol (2.50 kcal/mol) or reaction B with  E_act = 20.9 kJ/mol (5.00 kcal/mol).

The activation energies of the forward and reverse reactions of a system are 50.0 kJ/mol (12.0 kcal/mol) and 75 kJ/mol (17.9 kcal/mol), respectively. Create an energy diagram for this system and determine whether the forward reaction is endergonic or exergonic.

Label the energy diagram shown below:

Which of the following describes the reaction in the energy diagram below?

For the reaction

A + B → C + D

identify the arrow that represents the activation energy of the forward reaction.

Below are the potential energy profiles for three reactions. Which of the following statements is true?
