How Does Pressure and Temperature Affect the Chemical Potential of CH4?

AI Thread Summary
The discussion centers on calculating the change in chemical potential of methane (CH4) as it transitions from an initial state of 1 atm and 298.15 K to a final state of 100 atm and 400 K. Participants are encouraged to use the ideal gas law to determine the change in Gibbs free energy (delta G) for this transformation. The focus is on understanding how pressure and temperature variations impact the chemical potential of CH4. The problem emphasizes the need for precise calculations in thermodynamics involving pure substances. Overall, the discussion aims to clarify the relationship between these variables in the context of methane's behavior under specified conditions.

Homework Statement




Calculate the change of chemical potential of CH4 in a transformation from the initial
state using the ideal gas law. σi={pi=1atm, Ti=298.15K} to the final state σf={pf=100atm, Tf=400K}.

any ideas?

Since this appears to be a pure substance, let me rephrase the question another way:

What is delta G for the process of expanding one mole of methane from the initial state to the final state?

Thread 'Confusion regarding a chemical kinetics problem'

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...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

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...
