Q: Which of the following statements is true regarding the activation energy (Ea) of a reaction?
Solution:
The activation energy (Ea) of a reaction is always positive.
Steps: 4
Show Steps
Step 1: Understand what activation energy (Ea) means. It is the minimum energy required for a chemical reaction to occur.
Step 2: Recognize that energy is always needed to break bonds in reactants before new bonds can form in products.
Step 3: Realize that since energy must be added to start a reaction, the activation energy cannot be zero or negative.
Step 4: Conclude that the activation energy (Ea) is always a positive value because it represents the energy barrier that must be overcome.
