Worked Solution & Example Answer:The Boltzmann distribution for the hydrogenation of an alkene nickel at a particular temperature in the absence of a catalyst is shown - CIE - A-Level Chemistry - Question 11 - 2017 - Paper 1
Step 1
the shape of the Boltzmann distribution
Answer
When a catalyst, such as nickel, is added to a reaction, it lowers the activation energy required for the reaction to proceed. This affects the shape of the Boltzmann distribution by making it broader; fewer molecules will need higher energy to react.
