Question
An acid-catalyzed reaction that is first-order in H+ has a rate of 5.0 × 10–6 M s-1 when carried out in a buffer with pH = 5.0. What is the rate when the reaction is carried out with all reactant concentrations the same, but with the pH buffered at 5.5?
A.✓ Correct
1.6 × 10–6 M s–1
B.
4.5 × 10–6 M s–1
C.
5.5 × 10–6 M s–1
D.
1.6 × 10–5 M s–1
