Question

I need some physics math help at a calculus level

Answer 1

In lab we experimentally derived the enthalpy of naphthalene (which I got 5154.944 kJ/mol) and are told that we now need to correct for constant temperature, constant pressure, and gas ideality. We did the experiment at constant volume. We are given the equation that is in the first attachment to correct for constant temperature. The second attachment has the corresponding paragraph that "explains" the equation. I already solved for Cp of the balanced equation and got -82.7348 J/mol*K. I really don't understand how to plug in these numbers, and as a result how to solve it. Suffice it to say, I barely made it through calc by the skin of my nose.

Answer 2

I keep thinking that I should be plugging in my value of enthalpy to correct it, but it doesn't really make sense to plug it in for delta H

Answer 3

\[\Delta Cp\] is essentially a constant, right? So it can be pulled out of the integral?

Answer 4

I hope you are not trying to get answers for a test or a quiz or anything like that, You do realize that that would not be the right thing to do right? I sure hope so, You need to improve with trying to ask people to explain the question you have instead of just giving you the answers than you learn absolutely noting once so ever. =}

Answer 5

It is so frustrating to be struggling with this lab report for the last week, trying to word my problem in a way that makes sense. I assure you, this isn't for a test or quiz and I AM trying to understand this, hence my trying to slowly work through what I do know. I literally spent the last 5 minutes typing up responses to you and then deleting them because they seemed to harsh. All I have to say is, learn to spell and don't use that stupid face at the end of the post because it doesn't make it better. =} (see, it does nothing)
