1. The rate constant nearly doubles for some reactions when there is an increase in temperature from 17ºC to 32ºC. Calculate the activation energy.
2. In a certain tap-water sample, [H^+] = 4.6 X 10^-7 M. What is the concentration of OH^-?
3. When 50mL of 1.000 M HCl is titrated with 1.000 M NaOH, the pH increases. What is the pH of the solution after 49.99 mL of 1.000 M NaOH has been added?© BrainMass Inc. brainmass.com November 30, 2021, 1:55 am ad1c9bdddf
It finds the activation energyof the reaction given its rate constant change with temperature. It also shows how to calculate the pH of the solution during the tiration process.
