Question 1
What does the exponent 'm' in the rate law signify?
- It represents the rate constant
- It indicates the order of reaction with respect to A
- It indicates the concentration of reactant
💡 Hint: Think about it relating to the concentration and rate relationship.
Question 2
True or False: The orders of reaction are always equal to the coefficients in the balanced chemical equation.
- True
- False
💡 Hint: Consider how you derive order from data.

Challenge Problems
Push your limits with challenges.
Question 1
Given a reaction where the rate quadruples when [A] is doubled, determine the order of the reaction with respect to A and explain your reasoning.
💡 Hint: Compare rate changes to concentration changes.
Question 2
If a runs an experiment with concentrations of [A] = 0.1 M and [B] = 0.1 M yielding a rate of 5 x 10^-3 M/s, how would changes to [B] affect the overall rate if it’s second-order?
💡 Hint: Use the known order to correlate changes.
