Re: Study Tips

Hi!!
I agree with the other reply! I also like to look up videos that explain the conceptual parts of the topics in a more simplified way!
You're going to do great! :)

Re: Textbook 7D.1

Hi!
I believe that the equation ln(k2/k1) = (Ea/R)*(1/T1 - 1/T2) is used because you are given to rate constants and two temperatures and asked to find Ea. I think that as long as you know the information given in the problem, you should be able to figure out which equation to use!

Re: Week 10 Homework Question 14

Hi!
The way that I isolated T2 is by distributing the value I got for Ea/R into the parentheses that contain (1/T1-1/T2) and then multiplying T2 to both sides so that I could just divide both sides by the value that was attached to T2!
I hope this helps :)

Re: Finding the rate constant using a table

Hi, If you are given the overall rate law of the reaction, all you need to do is take the data from any trial given in the experimental data table and plug into the equation rate=k[A]^x[B]^y and solve for k. If you are given the data of a reaction with rates in an experimental data table, you first ...

Question 5 HW week 9 + 10

The reaciton A + B-->C + D, rate=k[A][B]^2, has an initial rate of 0.065 M/s. What will the inital rate be if [A] is halved and [B] is doubled? I am stuck on how to start solving this problem, any guidance would be appreciated! :D
