Question 1
Consider a reaction where doubling the concentration of Reactant X results in a tripling of the rate. What is the order with respect to Reactant X? Justify your answer.
💡 Hint: Think about how changes in concentration translate into changes in reaction speed.
Question 2
You conducted an experiment and observed the following rates: [A] = 0.1 M, Rate = 2.0; [B] = 0.1 M, Rate = 2.0. If you modified the concentration of A to 0.2 M and the rate became 4.0, what can you say about the order concerning A?
💡 Hint: Examine how the concentration changes influence the reaction rate.
