Question 1
Easy
What happens to the rate of a zero-order reaction if the concentration of the reactant is doubled?
💡 Hint: Think about what ‘zero-order’ means for the rate.
Question 2
Easy
In a first-order reaction, how does the rate change if the reactant concentration is halved?
💡 Hint: Remember, first-order means a direct relationship.

Question 1
Consider the reaction A + B → Products. In experiment one, [A] = 1 M, [B] = 2 M and the rate is 2 M/s. In experiment two, [A] is increased to 2 M while [B] remains constant and the rate is 4 M/s. What is the order of reaction with respect to A?
💡 Hint: Analyze how changes in the concentration of A affected the rate.
Question 2
Given experiments showing [A] = 0.5 M, [B] = 0.5 M results in a rate of 0.1 M/s, and when [B] is doubled to 1 M, the rate increases to 0.4 M/s, determine the order for B.
💡 Hint: Use the rate change in terms of concentration changes.
