Explain the relationship between activation energy and react

Explain the relationship between activation energy and reaction rate. For example, how would an increase in activation energy affect reaction rate? How do biological systems differ from lab settings when considering these chemical variables?

Solution

Answer:

Activation energy and reaction rates are inversely related.

Lower the activation energy higher the rate of reaction. Activation energy is the minimum energy needed to cause a chemical reaction by collision of particles. Increase in activation energy means a system needs larger energy input for a reaction to happen, therefore the rate of reaction decreases.

In biological systems catalysts- Enzymes take care of this job.They increase the rate of reaction by lowering the activation energy . They lower the activation energy by bringing together the reacting molecules and facilitating the formation products.
