Problem

Which of the following can lower the activation energy for a reaction?

a. Increasing the concentration of reactants
b. Raising the temperature of the reaction
c. Adding a suitable catalyst
d. Removing products as the reaction proceeds
e. Increasing pressure

Solution

We’re being asked to determine which of the following can lower the activation energy for a reaction.


Recall that the activation energy (Ea) is the difference in energy between reactants and transition state. As shown in the diagram below:


Let's take a look at each statement given:
