Help with P. Chem problem

What exactly is your problem?
>or put them in terms of my manipulating variable
I don't understand what you mean.

The deriving operation?

Tip: Whenever deriving partially in your mind replace the non regarded variables with a constant (I for some reason always use 3), this makes it a lot easier to understand what's going on.

You don't ignore them, they become constants, H is a sum of products, deriving a sum is equal to the sum of the derived element. a does not have the variable connected to it, so d/dT (a) = 0.
b is a constant, constants in a product are not affected, d/dT (bT) = b d/dt(T) = b*1 = b
IN the same way it becomes c*2T and d*-(1/T^2)

Yes they are derivations with respect to the variable listed. I'm hoping I'm on the right track.

Don't forget the minus at a), also it workss via quotient rule but can be done easier as n R and T are constants, so it's nRT*d/dV(1/V)

f) plain wrong, r is constant, it cannot disappear, then use the standard product rule for sin(theta)cos(theta)

Thanks so much. F was f-ed up.

The answer is 12 dude

Derive you fuck.
