okay, thanks for replying again. Just one more thing, at negative temperature is the entropy 0? Because I can't do ln for a negative number. I used this equation : Δr S Tf= Δr S Ti + Δr CP ln(Tf / Ti)

in a follow up question I was asked "obtain the reaction entropy, ∆rS, for such a temperature" (which I calculated to be -1725.15k) So I tried using this: Δr S0 Tf= Δr S0 Ti + Δr CP ln(Tf / Ti) but I can't do ln for a negative number so is my temperature calculation wrong?

oh yeah, I totally missed that. does this number seem reasonable ?

Homework Statement Organic life is based on complex organic molecules formed from smaller ones during a long evolution. Using data in Appendix 2, investigate one such reaction: 2 C2H6 (g) → C4H10 (g) + H2 (g) (a) Calculate ∆rH and ∆rS for such a reaction under standard conditions (Po = 1 bar...

hey guys one more thing. For part B) For He at 300 K, obtain speeds v1 and v2 for which F(v) = Fmax/2, and then calculate the fraction of particles with speeds v between v1 and v2. Analyze and conclude if this fraction depends on T and m0, and if yes, how exactly by calculating it for He at...

Thanks so much for your help.

alright thank you for your help. And, I will post def. post the solution here

yes that makes sense but I am not sure we are allowed to do that. But still ,I will use your method if I don't get it resolved by tomorrow. Anyways, do you think there is a way to to isolate for V (from my work above)? you don't have to tell me the answer, yes/no will suffice as I don't really...

yea I did use that equation and when I rearrange it would leave me with this: so now I just got to solve for V tho? I am on the right track? correct?

Also I calculated Fmax based on : Now I know I got to divide this value by 2 and solve the equation above but i can't seem to isolate V

alright so this is what I have so far Original equation and doing some rearranging, I get: got this far?? Is this correct so far? I can't seem to isolate V

Yea I did that for part A) but how am i suppose to count velocity at Fmax/2

Well not much, I tried isolating for V from that equation I provided above but I couldn't get it by it self. And, the V(most probable) I got = 1116.74m/s
