Equations for isothermal reactions

Postby Acosta_Leah_1J » Wed Feb 14, 2024 9:46 am

we have taken a look at a lot of different equations for different conditions. Does any one have any tips on how to remember which equations belong to isothermal reactions?

Between the two work equations, w=-p(delta v) and w=-nRTln(v1/v2), you use the first one when the system experiences constant pressure. The second one is used when the system is under reversible and isothermal conditions (constant temperature).

It is also helpful to remember that isothermal reactions have a net zero change in internal energy so you can calculate work/q based on this.

A way to remember which equations are applied to which isothermal reactions, we focus on identifying the specific conditions of each equation. Equations that have terms "isothermal" "constant temp" or "T = constant" will apply to reactions with constant temp.
