equations

Postby Fayt Sarreal 1G » Thu Feb 09, 2017 3:42 pm

There are various ways to calculate the work of an isobaric reaction such as w=-P(deltaV), w=-nR(deltaT), and w=-(deltan)RT. This also goes for calculating change in entropy, enthalpy, and heat. I am aware that some equations are listed but not all of them are. Will we be given the different equations to calculate these things or will we have to memorize them?

Thank you!

I believe that we will be given w = -(Pex)(DeltaV), though this is a very easy equation to memorize.

We can easily find the other equations by simply substituting some values.

We know that PV = nRT. Therefore, by applying a change in one value to each side, P(DeltaV) = (DeltaN)RT = nR(DeltaT).
