3/2R and 5/2R

Postby Noh_Jasmine_1J » Mon Feb 11, 2019 3:18 pm

do you use 3/2R and 5/2R when calculating change in entropy when there is a temperature change? are there any other situations where you would use them?

3/2R is for Cv and 5/2R is for Cp. It's on the constants sheet

For this midterm, I think the only time you'll use them is in deltaS = nC ln (T2/T1), depending on if it's constant pressure or volume.
