10 Questions
Define activation energy.
Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.
How does activation energy affect the rate of a chemical reaction?
Activation energy determines the rate of a chemical reaction; higher activation energy means the reaction is slower.
Explain why some reactions have high activation energies.
Reactions with high activation energies have more complex or unstable reactants that require more energy to initiate the reaction.
What happens to a chemical reaction if the activation energy is lowered?
Lowering the activation energy speeds up the reaction as it becomes easier for the reactants to overcome the energy barrier.
Discuss the significance of activation energy in biological processes.
In biological processes, activation energy plays a crucial role in determining the efficiency and speed of biochemical reactions necessary for life.
A catalyst increases the activation energy required for a chemical reaction to occur.
False
A catalyst changes the final outcome of a chemical reaction.
False
The presence of a catalyst alters the equilibrium constant of a chemical reaction.
False
An inhibitor and a catalyst have opposite effects on a chemical reaction.
True
Catalysts provide additional energy to start a chemical reaction.
False
Learn about the minimum energy required for molecules to result in a chemical reaction known as activation energy.
