The Gargoyles roughly pushed them into the opening, where there was a platform, and then flew away and left them.

This helps so much!! I have ALEK quizzes and since I’m taking the summer session, he didn’t put this on the practice HW on ALEK so seeing people get this on the quiz put me in for a loop but this helped me understand the concept more and hopefully I can get that one more 100% I need! Thank you!!

For anyone confused about the last part. First he solved for k given experiment 1. Given rate equation: Rate= k[P4]^2. First isolate k: K=rate/[P4]^2. Then plug in experiment 1 data which is k=(3.19*10^-4)/(0.0110)^2 = 2.636 = 2.64. Then plug in 2.64 to the original rate equation to look like this: Rate = 2.64*[P4]^2. Question c is asking to solve for the rate given P4 and H2 concentrations. Plug in both (H2 will end up being just 1 since H2^0 = 1 which is why I didn't write it before). The equation should look like this: Rate = 2.64*[0.242]^2. This equals 0.155. Thanks!

How did you get 1.86?
@TonyStJohn
@TonyStJohn 2 месяца назад
1.86 is the constant Kf value for water - so it's just a given constant for water.
@chelsea9013
@chelsea9013 2 месяца назад
Thanks a million, Tony! So why couldn't we use the concentration of the Br- ion (Ksp) in the final ice table for the last calculation?
@TonyStJohn
@TonyStJohn 2 месяца назад
Hi! If I'm understanding your question correctly - I think the easiest explanation is that we should treat these as two separate problems, and in the second one we're really setting things up "from scratch" aka "starting the calculation over" - you are right to think that the Br- ion is going into solution based on the Ksp calculation, but that is sort of being automatically taken into account in the second calculation when we combine the equilibrium expressions. I hope that makes at least a little bit of sense!
@chelsea9013
@chelsea9013 2 месяца назад
@@TonyStJohn I understand, since we multiplied our two K values it considers the Br- concentration. Thank you for the speedy response!
