Question 1.
What happens to the rate of a zero-order reaction if the concentration of the reactant is doubled?
Show hintHide hint
Think about what ‘zero-order’ means for the rate.
Question 2.
In a first-order reaction, how does the rate change if the reactant concentration is halved?
Show hintHide hint
Remember, first-order means a direct relationship.
3Question 3.
What is the order of a reaction if doubling the concentration of a reactant doubles the reaction rate?
- Zero Order
- First Order
- Second Order
Show hintHide hint
Think about the direct correlation between concentration and rate.
4Question 4.
True or False: The zero-order reaction rate is affected by changes in the concentration of the reactants.
- True
- False
Show hintHide hint
Remember the definition of zero-order reactions?
Question 5.
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?
Show hintHide hint
Analyze how changes in the concentration of A affected the rate.
Question 6.
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.
Show hintHide hint
Use the rate change in terms of concentration changes.
