Question 1
A pilot study shows that doubling the concentration of hydrochloric acid in a reaction with zinc increased the rate of hydrogen gas production by 75%. Assuming the relationship remains linear, what would be the expected increase in reaction rate if the concentration is tripled?
💡 Hint: Look at the initial increase to predict the new rate.
Question 2
If a given reaction has an activation energy of 50 kJ/mol and is performed under standard conditions at two different concentrations, discuss how the reaction rate might vary based on your knowledge of concentration and reaction mechanics.
💡 Hint: Consider both concentration and collision theory together to analyze the rate.
