Week 3 Assignment Acid Have Equilibria
DH and Kinetics
▼
Correct
Expressed in terms of z, y, and z, the rate law is as follows:
rate = kryz
By substituting the actual species from the reaction, the expression becomes
rate= k[IO3 ][SO32][H+]
Part B
By what factor will the rate of the reaction change if the pH decreases from 5.50 to 2.00?
Express your answer numerically using two significant figures.
