ΔU= 3/2nRT

Will we ever need to use ΔU=3/2nrt?

I haven't really come across any problems using this equation.

For the most part, that equation is used to show that ΔU = 0 during isothermal reactions. Since ΔT = 0 and ΔU = 3/2nrΔT, ΔU = 0.

We can use it, for ideal gases and monoatomic ones, but with the plethora of equations we have, we would mostly never come across a time to use it.

We rarely need to use this equation but since professor Lavelle did mention it in class, it may be a good idea to know anyways.

I have never really come across any question where I had to use this equation. It is basically another way to state the fact that delta U=0 for an isothermal, reversible expansion. You might want to learn it just in case.
