Q 8.11

Postby Belle Calforda3f » Mon Jan 15, 2018 9:03 pm

I thought the value for R was .0821, where is the answer book getting 8.314 J/KxMOL?

Hi. So I think the difference between the R value of 0.08206 or (0.0821) and the R value the book used is the pressure unit. The R=8.314 is using kPa vs the R= 0.0821 is using atm
Straight from my constant sheet from last quarter:
R = 8.314 L ∙ kPa ∙ K−1∙ mol−1
R = 0.08206 L ∙ atm ∙ K−1∙ mol−1
Hope that helps.
