Worked Solution & Example Answer:The diagram represents the change in concentration of a reactant against time during a reversible chemical reaction - Scottish Highers Chemistry - Question 6 - 2023
Step 1
In which diagram below does the dotted line show the result of repeating the reaction using a catalyst?
Answer
The correct answer is B. When a catalyst is used, it lowers the activation energy of the reaction, allowing it to reach equilibrium more quickly. In diagram B, the dotted line indicates a faster rate of approach to the equilibrium position than in the original reaction, which is consistent with the use of a catalyst.
