Question

Energy required for start of a chemical reaction is

• A. Activation energy
• B. Entropy
• C. Potential energy
• D. Kinetic energy

Answer 1

The correct option is A Activation energy

Entropy is a measure of thermal energy.

Potential energy is the energy stored in an object at a particular height.

Kinetic energy is the energy stored in an object in motion.

Enzymes are proteins which accelerate the rate of the reaction. The substrate and product have different energy state. The energy gap between the substrate and the product is known as activation energy which is the minimum energy required to initiate a reaction. The enzymes lower the activation energy and lead to the faster conversion of substrate to the product.

So, the correct answer is option A.
