Hey pls help me don't reject it

! ( plz answer was with explanation)

need help with part (iii) and (iv)  ANSWER TO PART (i) = -747.5 kJ ANSWER TO PART (ii) = -630 kJ/mol (iii) Briefly discuss the discrepancies in the values obtained in (i) and (ii) and the relative merits of the two approaches, both in general and for this particular case.  (iv) Do you anticipate that this reaction is spontaneous at low and at high temperatures respectively, briefly explain your reasoning.

can you answer question nine correct, please

(4) 2.50mol of Ar (ideal gas) initially at 298K and P = 1bar is heated until its volume is doubled. Find w done on the gas, q, AU, and AH if the process takes place at constant pressure, and P = Pext- = Find AS, ASsurr, and AStotal for surr spontaneous in those cases? Why? 1000K and Tsurr = 298K. Is the process

Good day Maam/Sir.. I hope you can help me with this one... Pleasseeee im begging you to answer not just 1 question pleaseee huhuh only few expert questions left in my account.. in return I promise to give helpful rating promiseee

i need the answer quickly

Compute the entropy change in the surroundings when 2.0 mol of H2O2 (I1) is formed from H2 and 02 (liquid) at 1 bar and 298 K. Notes: (i)The reaction to occur slowly. (ii) A table of standard thermodynamic quantities tells us that AH = -188 kJ/mol; the reaction is exothermic.

need explanation in detailed typed don't copy from other sources I will downvote

Give detailed Solution with explanation needed..don't give Handwritten answer..don't use Ai for answering this

Please specify answer. Thanks!

Here is what I got for this HW assignment, and I was wondering if someone could point out any mistakes. . I was also wondering if someone could give me information about predicting sign of delta G, H and S. Thank you.

please help me with part b,d,f,h as they are all part of one question. I really want to make sure i get them right. I will highly consider giving thumbs up

Program is informing me that my answer of-458992.14 is not to the correct amount of significant figures.

Give me handwritten answer .

The heat of reaction at constant pressure is a state function. Correct?

question 4

Hello, can you help me understand the attached problem? I keep filling in the answers incorrectly

When most elastomeric polymers (e.g., a rubber band)are stretched, the molecules become more ordered, asillustrated here: Suppose you stretch a rubber band. (a) Do you expect theentropy of the system to increase or decrease? (b) If therubber band were stretched isothermally, would heat needto be absorbed or emitted to maintain constant temperature?(c) Try this experiment: Stretch a rubber band andwait a moment. Then place the stretched rubber band onyour upper lip, and let it return suddenly to its unstretchedstate (remember to keep holding on!). What do you observe?Are your observations consistent with your answerto part (b)?

Give typed explanation not a single word hand written otherwise leave it    Correct answer from answer key: 345
