Platinum nanoparticles are often used as catalysts and has shown that the activation energy often depends on the size of the platinum particle. For example for dehydration of propane is activation energy 100 kJ/mol for platinum particles of 10 nm radius while it is 77 kJ/mol for platinum particles of radius 3 nm. How much faster is the reaction which takes place with the help of the smaller particles?
