Question
1. A reaction in this experiment is started when 3.00 mL of 0.100 M t-butyl chloride is diluted to a final volume of 10.0 mL. After 150 sec, t1/10 has been reached.
a. What is the concentration of t-butyl chloride (molarity) at the start of the reaction?
b. What is the value of the rate constant (k) if the reaction is first order?
c. What is the value of the rate constant (k) if the reaction is second order?
2. The reaction in #1 is repeated, but this time 6.00 mL of 0.100 M t-butyl chloride is diluted to a final volume of 10.0 mL.
a. Using the k value from your answer to #1b, what t1/10 should be expected if the reaction is first order?
b. Using the k value from your answer to #1c, what t1/10 should be expected if the reaction is second order?
Explanation / Answer
a) The concentration of t-butyl chloride at the start of the reaction is high after dilution decreases its concentration
