In your laboratory you're studying a chemical reaction that follows the general rate law: rate = k[A]2. Initial experiments show a rate of 0.0009784 M/s when [A] = 0.871 M at 279 K. You add a catalyst to the reaction, which is known to change the activation energy of the process by 4.3 kJ. What will the rate of the reaction be with the catalyst when [A] = 0.0547 M at 323 K? Assume that the Arrhenius factor for this reaction has been determined to be 0.729 M-1s-1.

What is the molarity of acetic acid, CH3COOH (MM= 60.0) in vinegar if a 5.00mL sample of vinegar requires 22.50mL of a 0.195M NaOH solution to neutralize it?
A sample of chlorine has two naturally occuring isotopes, the isotope Cl-35 makes up 75.8% of the sample, and the isotope cl-37 makes up 24.3 of the sample. Which of the following statements is true
What is the pH of a dilute 0.00336 M solution of formic acid? Formic acid is monoprotic with a Ka of 1.70 x 10-4. You should use the quadratic equation for this one because the solution is very dilute.
