AI Thread Summary
The discussion focuses on calculating the heat capacities (Cp and Cv) of nitrogen and carbon dioxide as real gases. The user references an equation for Cv involving derivatives of the second virial coefficient (B) with respect to temperature. They express difficulty in solving the differential equation component of the equation, specifically the term '(2(∂B/∂T) + T(∂²B/∂T²)P'. The user seeks guidance on how to approach this problem, noting their unfamiliarity with solving second-order differential equations. The thread highlights the need for assistance in applying thermodynamic principles to real gas behavior.

Homework Statement


Hello there,

I was given a tasks to find Cp and Cv of nitrogen and carbon dioxide in real gas situation.


Homework Equations



From what i could find, the suitable equation would be:

Cv = Cv° - (2(∂B/∂T) + T(∂²B/∂T²)P



The Attempt at a Solution



The problem is I couldn't find a way to solve the

'(2(∂B/∂T) + T(∂²B/∂T²)P'

part of equation. Any guidance will be highly appreciated. Thanks.

This is a differential equation of 2nd order. I myself don't know how to solve differential equation of 2nd order but you can use calculators to solve it.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
