Q: If the activation energy of a reaction is increased, what happens to the rate constant k?
Solution:
According to the Arrhenius equation, an increase in activation energy results in a decrease in the rate constant k.
Steps: 5
Show Steps
Step 1: Understand what activation energy is. It is the minimum energy required for a reaction to occur.
Step 2: Learn about the rate constant k. It is a number that tells us how fast a reaction happens.
Step 3: Familiarize yourself with the Arrhenius equation, which relates the rate constant k to activation energy (Ea) and temperature (T).
Step 4: Note that the Arrhenius equation shows that as activation energy (Ea) increases, the value of k decreases.
Step 5: Conclude that if the activation energy of a reaction is increased, the rate constant k will decrease.
