Hi Dr. Uma,

I don't understand question 33. Isn't neon an inert gas? Why would it affect the reaction quotient and the reaction rate? What kind of situation is this? When I did other equilibrium problems, inert gases wouldn't affect the reaction. 

Hi Dr. Uma,

I don't understand question 40. I got the final value of 14.9 or around 15 degrees Celsius, so I would assume that the answer would be c (greater than 14). However, the answer key says that it is B. How come?

 

nevermind i understand it now

Hi, I was confused on two questions I got wrong from the quiz 6.1. Could you please explain how to solve these?

I will edit it.
Thanks Sid.

Quote from: Siddharth_Pendyala on April 27, 2025, 01:47:37 PMI was doing my quiz and saw this problem. How can the answer be Platinum (Pt) when it conducts electricity alone? Also, Pt has a melting point at 1768°C, not 801°C, which is the melting point of NaCl - I think the question's correct answer should be NaCl. Am I doing something wrong? I've flagged the question.

I know I already asked you this in class, but I don't know if I was clear enough. This is what she said, which made me confused.

ohhh! I see. I was thinking of something else; thank you!
